Funny joke. You need to be English to get the Man United joke, but you can change the team to anything.

This guy really hates Manchester united fans, whenever he sees one, he goes onto the pavement and runs them over.
One day, he picks up a hitch-hiker, who happens to be the priest of the local church.The priest gets into the back seat. So as the guy drives the priest to church, he sees a Man United fan, so he swerves to hit him, but he thinks to himself, If I hit this guy with the priest in the back, I'll go to hell, so he swerves out of the way, and he hears a bang from the back seat. he says to the priest,
"I was going to hit that Man U fan but I swerved out of the way in time." The priest replies,
"Don't worry, i got the F with the door!"
