So the guy receives a phone call from his girlfriend. She says, "Honey, you gotta come over quick! I'm working on a puzzle and I can't quite put it together!"
The guy hangs up the phone and hops into his car. On the way over, the girlfriend calls again. The guy replies, "Yes, dear, what is it?"
The girlfriend says, "I almost forgot to tell you, the picture on the cover of the box is a tiger!"
So the guy arrives and sees the puzzle strewn across the coffee table. He sighs and says, "Honey, you know I love you. But go into the kitchen, and make yourself a cup of tea. We'll then put the Frosted Flakes back into the box."
(But you knew that one.)
