When a sneeze sneaks up on me, it tends to be very high-pitched.  The kids think this is hilarious.

Mrs. B:  ...so you carry the...the...AT-TEEEEW!

Almost the entire class:  (imitating my sneeze)  AT-TEEEEW!  AT-TEEEEW!  AT-TEEEEW!  AT-TEEEEW!

Mrs. B:  Very funny.

Brandon:  That sounded like a laser gun battle in space!
