When Arthur waits to be called in for his "surprise" party, he is pacing back and forth in front of the house, but this house doesn't even resemble the Heffernan house we see at the beginning of nearly every show.
Arthur: They got hot wings here that'll singe your short hairs right off.
Doug: I gotta tell you I am not crazy about the way you answer the phone.
Carrie: Can you beleive he's turning 75? We should do something special.
Doug: Chip in for a hooker?
Carrie: (about Arthur) So you handshake him a few stuffed mushrooms. I've been doing it since I was a kid.
Doug: Oh, really? You know what, why stop there? You know, why don't I French kiss him Jell-O? That'll be good.
The German episode title is "Geburtstagskind gesucht", meaning "Birthday Boy Sought".
When Arthur is watching TV in his room and says "this Screech has painted himself into quite a corner," he is referring to the nerdy character played by Dustin Diamond on Saved by the Bell. Leah Remini had a role on that show for six episodes in 1991.
