For an extra gross factor, false start and tell the students to pass there can (with their sock on it) down the line one person. This means they are drinking through someone else's sock! Great to watch!
this game is a classic. it is disgusting but surely one that the students will talk about for a long time. when we played it one of our contestants had just come from lacrosse practice and his socks were extra gross. our students still talk about that one!
