I don't know that anyone has ever really taken the time to notice but given that my wife is absolutely horrified at someone regurgitating we notice that there is an abnormally high number of movies, especially comedies, where at some point in the movie it involves someone throwing up, tossing their cookies, whatever you want to term it as.
My question is WHY? What's so funny about someone throwing up? Even non-comedies such as "Remember the Titans". Also has anyone else noticed this in modern movies?
