The old age pensioners that left at the end of the first film come back to earth to visit their relatives. Will they all decide to go back to the planet where no-one grows old, or will they be tempted to stay back on earth?

Art Selwyn: Joe loved the beach.
Ben Lucket: He didn't give a shit about the beach. It was them smooth legged girls in them dental floss bikinis, that's what he liked.
Ruby: Most people our age are a pain in the ass.
Bernie: Most people our age are *dead*.
Art Selwyn: There's no justice! If there were, it'd be *me* in there instead of her! *I'd* trade places with *her* in a *heartbeat*!
Ben Lucket: Last one in is a pantywaist!
Jack Bonner: You're my favorite Martian.
Joe Finley: I'm so tired.
Alma Finley: [cries] Then go ahead and rest dear.
Doctor: Mr. Selwyn?
Art Selwyn: [about his wife, Bess] That's me, Doctor! How is she?
Doctor: She's fine, considering her age. And the fact that she's six weeks pregnant.
Ben Lucket: [Chuckles, and to Art says] Why you smutty ol' devil.
Doctor: [Shaking Art's hand who's babbling "Pregnant?"] Very impressive, Mr. Selwyn. This one's definitely going in the books.
[Art is gladly congratulated by his friends]
Ruby: You know, when you want to, you can sure do a good impression of an old fart.
Bernie: Here is an eagle who just found out his teenage daughter is pregnant.
Art Selwyn: Beautiful beach, a sunny day and good friends. What more can a man ask for?
Joe Finley: [Pointing to young girls in bikinis] Can I have some of that please?
Art Selwyn: How'd you guys sleep?
Joe Finley: Alma didn't sleep a wink.
Art Selwyn: You're kidding.
Joe Finley: No. Neither did I.
Art Selwyn: You dog!
[about the pleasing shock of suddenly seeing all of his long-away friends again]
Bernie: For crying out loud!
Bernie: You work all your life, you pay taxes, you're a good citizen, and what do you end up with? A tight rug.
