Gum jokes

My favorite joke was: what's the difference between a teacher and a train?

A friend of mine chews gum, lays back to yawn, then chokes on the gum. Then I said, "God, what, you choking on dick?"

I’m gonna kick some gum and chew some ass... but I’m all out of ass.

Swallow cum, not gum.

What goes in soft and comes out hard?

Gum, you whore!

How do you get chewing gum out of your hair?

Cancer.

What's the difference between a teacher and a train?

The teacher says, "Spit out your gum," but a train says, "Chew chew!"
