Event - I've done this like a dozen times and its always been funny. You draw in like a mustach on someone whose passed out. But I did it to a guy who I didn't know had an job interview the next day. He scrubed the marker off, but it left a major red thing instead that looked almost as bad.
Apology - That was the last time I did it. When I think about it now its totally mean and whats that funny about it? I don't do it and I suggest no one else does. Sorry about that my friend. Please respond to let me know you got this.
