Here is a quick water spit-take I borrowed from the great Jerry Lewis. Basically you take a swig of water and start talking to people as the water flows out of your mouth and all over you. The key is to ignore it and pretend like nothing strange is happening. Then you take another swig and continue the process ad nauseam.
If you want to start slow, you can wait for a picnic where you are wearing a t-shirt and the clean up is easy. An advanced way of doing it is to wait for that all important annual meeting. Trust me, you will get tons of laughs but you might also get canned. (It’s actually funnier if you get no laughs).
An alternative version is the water drinking problem from airplane, where you take a glass of water and completely miss your mouth and instead splash your entire face.
PS. Make sure the water isn’t piping hot. Unless you pretend it is and start screaming. That’s funny 🙂
