"A guy driving a truck" joke

A guy driving a truck in the middle of nowhere picks up a hitch-hiker.
It gets dark and the hitch-hiker falls asleep. Suddenly bang, and the hitch-hiker wakes
up,"what the hell was that?". The truck driver replies,
"some kinda animal, go back to sleep."
Further the same thing again, bang, "What the hell was that?", "some kinda animal
again."
Further into the night, bang, bang, bang, "What the hell was that?",
"Some [ethnic] bastard!". "How terrible", says the hitch-hiker, "but there
were 3 bangs"
The truck driver replies, "Yeah, well I had to go through two fences to
get the bastard..."
