These are some of my favorites:
"I'm sorry, the batteries in my magic wand are dead and new ones are coming over on a slow boat from China."
"Do you want a little cheese with that whine?"
"This is not Burger King and you cannot have it your way"
"He/She is crazy as a bedbug"
"I'll be on you like ugly on an ape"
"No S#&@ Sherlock!"
