The fellow walked into a bar he had never been in before and ordered a drink.
He then asked the bartender if he enjoyed dumb-jock jokes.
 The beefy attendant leaned over the bar and fixed a withering glare on his customer.
"Listen, buddy," he growled.
"See those two big guys on the left? They’re professional football players.
And that huge fellow on your right is a world-class wrestler.
That guy in the corner is a champion weight-lifter.
And I lettered in three sports at Notre Dame.
Now," he continued, "are you absolutely positive you want to go ahead and tell your dumb-jock joke here?" "Nah, I guess not," the man replied.
"IÂ wouldn’t want to have to explain it five times."
