Peg's efforts to use Avon products to hide Edward's scars. Most notably the "hint of lavender" that turns his face purple.
Virtually every line delivered by Bill Boggs. His chirpy "Hey Edward, where are you going?" near the film's climax sends this Troper into fits every time!
Edward casually mentioning over dinner how Joyce attempted to seduce him. The entire family (save for Bill) does a double-take.
"We looked at where the salon is going to be. There's a place where you can have a make-up stand. And then she showed me the back room, where she took all her clothes off."
Made funnier by Bill not even noticing and continuing to ramble on about the pleasures of owning your own business.
The Barbeque scene especially the Shis kebob scene.
Bill: -checking the kebob- Ok Soup's on!!!
Edward: -mouth full- I thought it was Shish Kebob.
