Very Bad Jokes number 351 and 356 really got me rolling.

Number 356 reminded me of the bodyless head that got a job working for the state road department.
He was a flagman. They even put up signs that said "Flagman A head."

Punctuation is important:
What's that on the road ahead?
What's that on the road? Ahead?

Then there was the cat who sat watching a dog bark. The dog wasn't barking at the cat. He was just barking: Bark! Bark! Bark! Bark! Bark! Bark! Bark! Bark! When he paused for breath the cat said "That's easy for *you* to say."
