The birthday song (Someone's got a birthday I wonder who) the kids were singing at Dale's party, during his flashback was the same song Bill sang in "Hank and the Great Glass Elevator".

Luanne does not appear in this episode.
Octavio who made his first appearance in this episode, was mentioned back in "'Twas the Nut Before Christmas" by Dale.
As Dale is taking photos of Bobby's ventriloquist doll you can see he is taking the photo from the upper right of where Bobby is standing in his house. However the angle of which he takes the photo from would be impossible as it's to the left of their screen doors and there is no window or see-through material from that angle.
Whilst the old man in the retirement home is about to give Bobby the ventriloquist doll, there is a shot of just Bobby. In this shot you can see the jacket and hat on the coat rock and the coat is on the top rack. When we see both of them together the coat rack has another rack above the jacket now.
Dale: (gets caught trying to destroy Chip he inhales a cloth of chloroform) You'll never get an unconscious ma.............. (falls to the ground)
Hank: How'd you learn so much about golf?
Bobby: I've seen Happy Gilmore fifty times.
Hank: I hate Adam Sandler.
Chip: Yeah, he's all poo-poo jokes. You don't have to work blue to be funny.
Hank: Amen to that.
Dale: I would like to purchase some chloroform, a roll of duct tape, and this gagging bandana.
Hank: "Fluttering butterflies?" Not in this house.
Bill:(amazed when Bobby throws his voice) How do you do that Bobby?
Hank: (proudly) He's using show business.
Hank: My son's playing with dolls. There, I said it.
Dale: He's a sissy. There, I said that.
The song Bobby sings throughout this episode is "Frog Went A-Courting" which is an English language folk song. Its first known appearance is in Wedderburn's "Complaynt of Scotland" (1548).
