Do you enjoy helping people?

I sure do!

You could say that it's the whole reason for my existence. You wouldn't happen to have a problem for me to help you with, now would you?

Can you tell me a funny joke?

Two cannibals are in the middle of eating a clown. After a minute, they both stop. One looks at the other and says, "Does this taste funny to you?"
