Dave was bragging to his boss, day after day, "Let me tell you, I know everyone there is to know. Just name someone, anyone, and I know them."

Tired of his boasting, his boss called his bluff, "OK, Dave, how about Tom Cruise?"

"No dramas boss, Tom and I are old friends, and I can prove it."

So Dave and his boss fly out to Hollywood and knock on Tom Cruise's door, Tom Cruise opens it and shouts, "Dave! What's happening? Great to see you! Come on in for a beer!"

Although impressed, Dave's boss is still sceptical. After they leave Cruise's house, he tells Dave that he thinks him knowing Cruise was just lucky.

"No, no, just name anyone else," Dave says.

"President Obama," his boss quickly retorts.

"Yup," Dave says, "Old buddies, let's fly out to Washington," and off they go. At the White House, Obama spots Dave on the daily tour and gestures security to bring him and his boss into the Oval Office. As soon as they entered Obama rushed to embrace him calling, "Dave, what a surprise, I was just on my way to a meeting, but that can be delayed; you and your friend just get on over here let's have a cup of coffee first and catch up."

Well, the boss is very shaken by now but still not totally convinced.

After they leave the White House grounds he expresses his doubts to Dave, who again implores him to name anyone else.

"The Pope," his boss replies.

"Sure!" says Dave. "I've known the Pope for years." So off they fly to Rome.

Dave and his boss are assembled with the masses in St Peter's Square when Dave says, "This will never work. I can't catch the Pope's eye among all these people. Tell you what, I know all the guards so let me just go upstairs and I'll come out on the balcony with the Pope."

He disappears into the crowd headed toward the Vatican.

Sure enough, half an hour later Dave emerges with the Pope on the balcony, but by the time Dave returns, he finds that his boss has had a heart attack and is surrounded by paramedics.

Making his way to his boss' side, Dave asks him, "What happened?"

His boss looks up and says, "It was the final straw...you...and the Pope...came out on to the balcony and the man next to me...said...'Who the hell is that on the balcony with Dave?'"
