When we first see Dean having a shower and we see his hair, it is all flat, and then the second time we see him, it has been pulled into a mohawk.
The first time around when Sam and Dean come out of the Diner, a heavyset lady in red and her partner leave from a store next door. She can still be viewed in the background up to the time Dean bumps the blond. This couple does not show up in any of the subsequent loops. Even though the other loops don't show the couple coming out of the store, they should still be seen in the background.
During the second Tuesday discussion, after the blond bumps Dean there is a couple that walks across the screen from right to left, twice.
Sam: You don't remember any of this?
Dean: Any of what?
Sam: This. Like it's happened before?
Dean: You mean like deja vu?
Sam: No, like it's...like it's really happened before.
Dean: Yeah, like deja vu.
Sam: Forget about deja vu! I'm asking you if it feels like we're living yesterday all over again?
Dean: Okay, how is that not...?
Sam: Don't say it!
Dean: Rise and shine, Sammy!
(Sam, realizing it's Wednesday, gets up and hugs Dean)
Dean: How many Tuesdays did you have?
Dean: All right, all right. We'll go tonight after closing, get us a nice long look.
Sam: Wait… what? No!
Dean: Why not?
Sam: Uhhh…. Let's just go now – right now. Business hours! Nice and crowded.
Dean: My god, you're a freak.
Dean: I'm not gonna die; not today.
Sam: Twice now I've watched you die and I can't. I won't do it again, okay? You're just gonna have to believe me. Please?
Dean: Okay. I still think you're nuts, but... okay, whatever this is, we'll figure it out.
Sam: (looking at alarm playing Back in Time) It's Wednesday!
Dean: Yeah, which usually comes after Tuesday. Turn that thing off, would ya?
Sam: What, are you kidding? This isn't the most beautiful song you ever heard?
Dean: No! Geez, how many Tuesdays did you have?
(after Dean gets hit by a car)
Sam: And what?
Dean: Did it look cool, like in the movies?
Sam: You peed yourself.
Dean: Of course I peed myself. Man gets hit by a car, you think he has full control over his bladder? Come on!
Dean: You mean we can't even go out for breakfast?
Sam: You'll thank me when it's Wednesday.
Dean: Whatever that means.
Trickster: Whoever said Dean was the dysfunctional one has never seen you with a sharp object in your hands.
Trickster: Sam, there's a lesson here that I've been trying to drill into that freakish Cro-Magnon skull of yours.
Trickster: Dean's your weakness. The bad guys know it too. It's gonna be the death of you, Sam. Sometimes you've just gotta let people go.
Dean: Sammy, I get all tingly when you take control like that.
Sam: Yesterday was Tuesday but today is Tuesday too!
Dean: ...yeah. You're totally balanced.
Sam and Dean: (in unison) Yeah, right. Nice guess. Right you're a mind reader. Cut it out, Sam. Sam. You think you're being funny but you're being really, really childish. Sam Winchester wears makeup. Sam Winchester cries his way through sex. Sam Winchester keeps a ruler by the bed and every morning when he wakes up... okay, enough!
Sam: I had a weird dream.
Dean: Yeah? Clowns or midgets?
Music: Heat of the Moment (Asia), Back in Time (Huey Lewis and the News)
Injoke: The song that plays when Sam wakes up on each new Tuesday was sung by Eric Cartman in the South Park episode "Kenny Dies," in which Kenny (a character who dies and returns each episode) died for "real" and stayed that way for some time.
