Timmy hypnotizes Jimmy's mom into thinking she's "Mighty Mom." This is a reference to previous episodes featuring "Mighty Mom and Dyno Dad."

Mr. Crocker: Would anyone but an imp wear a hat this stupid? Oh, it looks good on you though.

This is a very, very lame spoof of the 1980 hit movie "Caddyshack" when Al Czervik, played by Rodney Dangerfield, says in the gift shop "Look at this hat. Looks like you get a free bowl of soup to go with it. This is the worst looking hat I ever saw" then he sees that the judge is wearing the same hat, and Al says "...oh, it looks good on you, though."

Sanjay: And I am not Sanjay. I am Yogi bear! I am smarter then the average bear.
Yogi bear is a cartoon character from 1960s.

Jimmy: Say Hello To My Big, Shiny Friend
This seems to be a goof on 'Scarface', a movie played by Al Pacino. The real line is "Say Hello To My Little Friend!"

Judy Neutron: Behind the refridgerator and beyond!
This quote was slightly taken from the show "Toy Story" where Buzz was showing off on Woody.

Timmy: I'm loopy! I'm loopy!
In case you didn't noticed the thing on Timmy's head was the helmet Jimmy used drain his brainpower in the episode "Normal Boy" and just like Jimmy, Timmy's IQ was reduced to that of a drooling brain-dead monkey. Also Timmy said the same Jimmy said when he became stupid. "I'm loopy!"

Cosmo: Pay no attention to the fairies behind the curtain.
This is a quote reference to the movie,
The Wizard of Oz, when Dorthy notices the source of the wizard and he says, "Pay no attention to that man behind the curtain. He's a nobody."
