It' not easy to re-invent the wheel...they say it takes true genius.So you have taken the imfamous "spit-take" and and made it your own.I have a friend who does this with food and a straight face while staring blank..he always seems to do it when I'm really trying to be serious about something..thank God thats not often.

I had a girlfriend who would, while using a straw, tilt her glass, pouring the drink down her front. It was pretty funny.

I have seen the same thing in some not-so-professional movies.
