"Night train to Frankfurt" joke
One day a man took the train from Paris to Frankfurt. When he got on the train, he went straight to the ticket-man and said, "Sir. I really need you to do me a favor, I have to get off this train in Mannheim, but I'm very tired and I'm sure that I will fall asleep. So what I want you to do is to wake me up in Mannheim because I have to close a business deal there and it is very important for me. Here are 100 francs for the favor."
He continued by saying, "But I warn you, sometimes when people wake me up I get really violent; but no matter what I do or say you got to get me off this train in Mannheim. Is that clear?"
So the ticket-man agreed and took the 100 francs. Later the man fell asleep... and when he woke up he realized that he was in Frankfurt!
He was so mad at the ticket-man that he ran over and started yelling: "Are you STUPID or something? I paid you 100 francs to wake me up and get me off at Mannheim. And you didn't! I want my money back!"
While the man was yelling, two other guys who were also on the train were looking at them.
One looked at the other and said "Jeez, that guy is really pissed off!"
The other replied, "Yeah. He's almost as mad as the guy they made get off the train at Mannheim last night."
