A really strong second episode of the series. According to TV.com, it is rated one of the best, I guess I can see why, but I hope things just get better from here on out. The pilot was okay, you saw potential, it got you interested in the characters, but this episode was really something.

We've got character development, and I actually found myself laughing almost all the way through. To Sheldon going to Penny's house in the middle of the night to clean to the gang trying to assemble the entertainment system in the end, this was a very hysterical episode. Even though Chuck Lorre gives us acquired humor, which means not for everyone, this is a good funny show.

I found myself warming up to all the characters quite quickly, which takes a while for me usually. I already feel like I've grown up with these characters though, and I can't wait to see the gang's next adventure!moreless

When Sheldon and Leonard go over to Penny's apartment to drop off a package that came for her, Sheldon is deeply disturbed when he sees how messy and disorganized her apartment appears. Later that night, when Leonard is sleeping, Sheldon sneaks into Penny's apartment to clean and organize it. Leonard catches him and tries to stop him, but gives up and helps him to clean up in the end. The next morning, Penny yells at them, prompting Leonard to ask Sheldon how she knew (Sheldon had left an organizational diagram for her closet). Sheldon apologizes to Penny but fails after remarking that Leonard is a "thorough and gentle lover." Later, Penny encounters Raj in the hallway and chats with him, finally realizing that the guys were just trying to help her. Leonard then apologizes, prompting Penny to hug him and say 'We're okay'. I'm glad I brought The Big Bang Theory now, I'm really enjoying it. I have to say I love the way each character is dressed the clothing is amazing - I think. I also love the each of the boys act difeerent infront of Penny. I love the wat Sheldon corrests everything in his nerdy way. I love the scene where Sheldon and Lenny carry Penny's package. I also love teh scenes inside Penny's apartment too, I foudn it hilarious when Penny finds out what the boys did. I also love the sarcasm on the show, I also lvoe teh Raj and Lenny scene and the scene with Raj and Howard - funny.moreless

The Superman conversation at the start had me in stitches and I'm definitely using the reference next time I watch Superman!

Them attempting to get the furniture up the stairs where absolutely hilarious!!

I LOVE SHELDON! His lines are absolutely genius - not one line he says isn't hilarious! Especially about Sex!

Sheldon is absolutely adorable - his lack of understanding of sarcasm is so cute - Penny's reaction is funny then Sheldons apology is absolutely HILARIOUS. I mean, I squealed with laughter, like everything to do with Sheldon!

I think we need more Howard and Rajesh too, they are just hilarious! Specially when Rajesh hugged Howard - oh too funny!!moreless

Where's my lightsaber?

This was one great episode, I was laughing constantly. It's nice to finally see a comedy show that is actually funny. Two and a half men lost it's touch, but this show is starting out great. I love the obsessive compulsive cleaning on a neighbor's apartment. It's one of those things that I would never do, but would seriously consider. The humor is fitting for a show about a bunch of geeks actually conversing with a hot chick. For a bunch of awkward nerds, the plot wasn't so predictable that it was painful to watch. The show has a lot of great energy and there seems to be a lot of hilarious possibilities.moreless

ADD QUOTES
- Penny: In my apartment, while I was sleeping!
  Sheldon: And snoring, and that's probably just a sinus infection, but it could be sleep apnea; you might want to see an otolaryngologist.
  (Penny stares at Sheldon)
  Sheldon: The throat doctor.
  Penny: And what kind of doctor removes shoes from asses?
  Sheldon: Depending on the depth, that's either a proctologist or a general surgeon.
  (Leonard holds up a piece of paper on which he has written "SARCASM")
  Sheldon: Oh.
  EDIT SHARE
- Sheldon: Excuse me, explain to me an organizational system where a tray of flatware on a couch is valid? Now, I'm just inferring that this is a couch, because the evidence suggests that the coffee table is having a tiny garage sale.
  EDIT SHARE
- Leonard: If you don't have any other plans, do you want to join us for Thai food and a Superman movie marathon?
  Penny: A marathon? Wow, how many Superman movies are there?
  Sheldon: You're kidding, right?
  EDIT SHARE
- Leonard: I guess we'll just bring it up ourselves.
  Sheldon: I hardly think so.
  Leonard: Why not?
  Sheldon: Well, we don't have a dolly, or lifting belts, or any measurable upper-body strength.
  Leonard: We don't need strength. We're physicists. We are the intellectual descendants of Archimedes. Give me a fulcrum and a lever, and I can move the Earth. (Trying to move the box) It's just a matter of... I don't have this. I don't have this. I don't have...
  Sheldon: Archimedes would be so proud.
  EDIT SHARE
- Sheldon: You do understand that our efforts here will in no way increase the odds of you having sexual congress with this woman?
  Leonard: Men do things for woman without expecting sex.
  Sheldon: Those would be men who just had sex.
  EDIT SHARE
- (they've lain Penny's box on the stairs)
  Leonard: Now we've got an inclined plane. The force required to lift is reduced by the sine of the angle of the stairs. Call it 30°, so about half.
  Sheldon: Exactly half.
  EDIT SHARE
- (Cleaning and organizing Penny's apartment at night)
  Sheldon: I couldn't sleep knowing that just outside my bedroom is our living room and just outside our living room is that hallway and immediately adjacent to that hallway is this! (showing Penny's messed up apartment)
  Leonard: Do you realize if Penny wakes up there's no reasonable explanation to why we are here?
  Sheldon: I just gave you a reasonable explanation.
  Leonard: No, no. You gave me an explanation. Its reasonableness will be determined by a jury of your peers.
  EDIT SHARE
- (everyone's trying to assemble Penny's new TV stand, reading the instructions)
  Wolowitz: Oh, boy! I was afraid of that!
  Leonard: What?
  Wolowitz: These instructions are a pictographic representation of the least imaginative way to assemble these components. This, right here, is why Sweden has no space program!

- Wolowitz: (after doing Dance Dance Revolution) Grab a napkin homey, you just got served.

- Sheldon: (in a very low voice, that is almost robotic) If you have time to lean, you have time to clean.
