Homer Scissorhands/Gags

Plot
The couch is in the Smithsonian Museum. The Simpsons sneak in (with Marge making a bigger hole in the glass after looking at Homer) and sneak through the museum, pretending to be janitors, mummies and camouflaging themselves against a painting. They then get to the couch to find it is protected by lasers. After spraying them to reveal them, they find holes exactly the same shape as themselves and fit through them and sit on the couch.
