Balloons
From Wittypedia
Much like baboons - in spelling if nothing else. Differing from them only slightly in their capacity as bits of rubber full of air which people sometimes have at parties.
Fun can be had by
...rubbing a balloon on your (or someone elses) hair
...then using the power of static electricity make it defy gravity and stick it to a wall
...and then going and watching a good comedy show.
