The Pope arrives in heaven, where St. Peter awaites him. St. Peter asks the Pope who he is.
The Pope : I am the Pope.
St. Peter: Who? There's no such name in my book.
The Pope : I'm the representative of God on Earth.
St. Peter: Does God have a representative? He didn't tell me...
The Pope : But I am the leader of the Catholic Church...
St. Peter: The Catholic church... Never heard of it... Wait, I'll check with the boss.
St. Peter walks away trough Heaven's Gate to talk with God.
St. Peter: There's a dude standing outside who claims he's your representative on earth.
God : I don't have a representative on earth, not that I know of... Wait, I'll ask Jesus.
(yells for Jesus)
Jesus : Yes father, what's up?
God and St. Peter explain the situation.
Jesus : Wait, I'll go outside and have a little chat with that fellow.
Ten minutes pass and Jesus reenters the room laughing out loud. After a few minutes St. Peter asks Jesus why he's laughing.
Jesus : Remember that fishing club I've started 2000 years ago? It still exists!
