If you choke a smurf, what color does it turn?

So I was looking through some old e-mails today, and I came across this. I thought it was funny. I don't remember how old this actually is. It was an old e-mail.... didn't have that date.

If you choke a smurf, what color does it turn?

A smurf is actually green, so it would turn a funny teal color. But how could you choke a smurf? They are to tiny, you would have to like,squeeze their little heads or something.

Anyways its just a thought.
