A very loud, unattractive, hard-faced tossa named WALLY walks into Kmart
with his two kids in tow, screaming obscenities at them all the way through
the entrance.

The door greeter says, "Good morning and welcome to Kmart, nice children
you've got there. Are they twins?"

The fat ugly tossa named WALLY stops screaming long enough to snarl: "Of
course they bloody aren't! The oldest is nine and the youngest is seven. Why
the hell would you think they're twins?..... Do you really think they look
alike, you d*ckhead?"

"Absolutely not," replies the greeter, "I just can't believe anyone would
shag you twice!"
