It's an old joke, it's long, but it's one of my favorites.

Dave and Mike are two friends and are hanging out, just talking and having a good time. Suddenly, the Prime Minister of Canada walks up to them with a huge smile on his face and says, "Hey Dave! Long time no see!" Mike is in shock and just listens to Dave and the PM chat, laugh and act lie they're old friends. After a bit, the PM says goodbye and walks off.

"You know the Prime Minister!?" Mike asks. "Of course," says Dave, "We've been friends for forever." So Mike asks him questions about it, like where they met, how they met, etc. While Mike is questioning Dave, lo and behold, the President of the United States walks up to them. "Dave! Holy moley! How you've been, man? Great to see you! When you coming by the White House again?" Mike's jaw drops. Once again, he listens to the POTUS and Dave chat and laugh. POTUS fist pounds Dave, says goodbye, and walks off.

"You know the President!?" Mike asks in total disbelief. "Of course," Dave answers, "I never told you that?" So of course, Mike starts questioning Dave about it. How did they meet, where, when, etc. Suddenly, Dave apologizes and says, "Mike, it's been good hanging out and everything but I gotta run. I've been invited by the pope to go hang out in the Vatican." Mike is understandably confused and doubtful.

"Ok, I can accept that you know both the president and the PM, but there's no way you know the Pope. That's impossible," Mike says. "It's true. We're old friends. In fact, I'll prove it. I'm allowed to bring a friend to Italy with me. Come along and I'll show you."

So Mike and Dave head over to Vatican City and Dave tells Mike to wait in the crowd in St. Peter's Square while the Pope does the Angelus prayer, the prayer he does every sunday at noon from his balcony. So Mike waits and keeps checking his watch, but begins to wonder where Dave went. Suddenly, chimes start ringing. 12 rings later, it's noon, and out steps the Pope, and would you believe that, to his side, is Dave! Mike nearly faints. The crowd is going crazy. Suddenly, a stranger grabs Mike, and says, "Oh Jesus. I can't believe it! It''s really him! But, who's that guy standing next to Dave?"
