Joel's line "Trumpy, you can do stupid things!" appears to be in response to Tommy's line "Trumpy, you can do magic things!", but Tommy didn't actually say his line until AFTER Joel says his.
During one of the scenes on the bridge of the Satellite of Love, items fly around randomly and the doors to the hallway open and close, with the hallway green screened in behind them. Some clothes fly around, and on one item (a pink jacket), a "hole" appears, showing the hallway. The jacket must have had a spot on it the same color as the green screen.
