Paddy and Murphy were watching a movie

Paddy and Murphy were watching a movie:
Paddy said to Murphy.
“I bet you €5 John Wayne falls off this horse and the horse goes over the cliff.”
Murphy said.
“Ok, Paddy.”
So there they are, watching the film and John Wayne falls off the horse and the horse goes over the cliff.
Paddy turns round to Murphy.
“I told you what would happen.”
Murphy said.
“You’re right Paddy, there you go €5.
Paddy thinks and at the end of the film, says.
“I feel pretty bad here Murphy.”
“Why that Paddy?”
“Because I’ve seen this film before.”
Murphy says.
“So have I, but I didn`t expect him to make the same mistake twice.”
