the best way to get a girl is to ignore her

Biff gets a call from his blonde girlfriend, Buffy. "I've got a problem," says Buffy. 
"What's the matter?" asks Biff.
"Well, I've bought this jigsaw puzzle, but it's too hard. None of the pieces fit together and I can't find any edges."
"What's the picture of?" asks Biff. 
"It's of a big Rooster," replies Buffy. 
"All right," says Biff, "I'll come over and have a look."

So he goes over to Buffy's house and Buffy greets him saying, "Thanks for coming over." 
Buffy leads Biff into her kitchen and shows him the jigsaw on the kitchen table. 
Biff looks at the jigsaw and then turns to Buffy and says, "For Pete's sake - put the Cornflakes back in the Box."
