Ok, first my appologies if this has been asked/answered before.But I did the searches and came up nada. So here goes.

I’ve heard since I was a kid about the ole’ “stick someone’s hand in a glass of warm water while they sleep and they’ll wet the bed” prank.  
Is this actually true? Seems unlikely that merely having a wet hand would induce such a thing.

Our own Cecil wrote a column about this very subject:

I’ve got a beautiful picture of this prank in action if anyone wants it sent to them.

They just did it on Malcolm yesterday on the tube. Threw some water on the kid to make it better.
