Sleep

I've had some trouble with sleep apnea. So I'm going to see a Dr at a sleep apnea clinic. The first question on the 10 page sleep history form is, "why are you coming to see us at this clinic?"
I came close, but did not put, "duh".
Instead I put, "and here's your sign."
My problem is that I don't know how to do a Sam Kennison scream with my computer.
