There's this guy in a bar that's saying he knows everybody, and will bet
anybody on it. So this guy walks up and says, "I bet you don't know Burt
Rynolds." He says come on, they hop a plane to Florida, show up at
Burt's door and Burt says, "Hi Bubba, how have you been? Come on in!"

On the flight back home the guy says, "I'll bet you another $100 you
don't know Bill Clinton." So they catch a flight to D.C. Sure enough
the walk into the oval office and Bill says "Hi Bubba, what are you
doing here? It's real nice to see you again!"

On the flight back home he says to Bubba,"I'll bet you double or
nothing you don't know the Pope." Bubba says "Look I don't really
want to take your money, me and the Pope go back a long way.
Really, pick somebody else." Figuring he's got Bubba on this
one, he insists, so they board a plane for Rome.

When they get to Vatican City, Bubba tells the guy, "Look, they aren't
going to let you in here with me. Stand right here and in 10 minutes I'll
be on that balcony with the Pope." After a little squabble he agrees.
Sure enough 10 mins. later there's Bubba on the balcony with the Pope.

Bubba looks down to see the guy passed out on the ground. He runs down
to see what's wrong and the guy says, "OK, you know Burt Rynolds, you know
the President, but when the guy behind me said, 'Hey, who's that guy up
there with Bubba' I passed out!"
