In this episode (which aired in 1994), Al is excited when old rerun of Dragnet airs. In real life, Ed O'Neill would later star in a revival of Dragnet, several years later, which ran for two seasons in 2003-2004.
In this Episode Marcy says that she never had a Barbie when she was a child because her parents never would let her have one. Yet there was an entire episode (Episode 27 / 214) devoted to Marcy's Barbie collection. In that episode she talks about having the Barbie's instead of real friends when she was a child.
Al said that Kelly is naturally blonde. However, there a few episodes on where she said that she isn't, just like Peggy isn't naturally red-haired.
Al: Ah, here's come Popeye.
Peg: (comes down the stairs humming "Blow the Man" down while holding her concertina)
Hey Al, you wanna try my squeezebox?
Al: No, Peg, you blew this man down a long time ago.
Auctioneer: And the next item up for bid, still in its original wrapper, the first issue of "Big 'Uns."
Jefferson: You don't have any money!
Al: You got 2 grand.
Jefferson: Al, that is money I took from Marcy for her birthday present.
Al: Jefferson, this is the first issue of "Big 'Uns." There's 40 pages. That's 80 'uns.
Jefferson: I hope the Barbie bidding stays low. I only brought 2 grand.
Al: 2 grand for a Barbie doll? A real woman isn't worth that much.
Auctioneer: Do I have another bid? Sold! For $3200, Michael Jackson's original nose.
Kelly: They say all blondes are dumb. But that's just a stereo system.
Kelly (watching "Superman"): What does that "S" on his chest stand for?
Kelly: Daddy, do you notice anything different about me?
Al: No, son.
Kelly: No, daddy, it's Kelly.
Al: Well tell her to come in!
Al: Now son, you've got two choices: you can get out, or, you can get the hell out!
(Al, posing as Jefferson, is lying next to Marcy in bed)
Marcy: Jefferson, rub my back.
(Al hesitantly moves his hand toward her)
Marcy: That's my chest.
(Al answers the door after Marcy furiously knocks)
Al: Hey, Marcy, I thought I heard some pecking.
Marcy: Outta my way, Swamp Gas!
Al: That's *Mr.* Swamp Gas to you.
Marcy: Jefferson, did you hear something?
Jefferson: Yeah, it was probably just Al falling from the window after having slept with you.
(They laugh at the thought)
(After finding out that the Barbie doll Jefferson got for Marcy is worth $50,000)
Al: Jefferson, $50,000! Well, what are we going to do?
(takes the doll from Al)
say 'goodbye' to you, and catch a plane to Aruba.
Jefferson's middle name is Milhouse.
The episode title is a reference to the movie Sleepless in Seattle.
