Fly in a lift
If you get into a lift, and there's a fly in there with you, and the lift goes up and the fly is flying around... why doesn't the bottom of the lift come up underneath the fly and smack it in the chin?
I mean obviously it doesn't so there must be a reason. So what is it?
first correct answer wins a cake.
ps - the answer is not 'because flies don't have chins'
