A Humor Lab without humor has little meaning. Just like many others, Sibe has his own sense of humor. Below you find some of his favorites showing that comedy is impossible without tragedie (and vice versa):

Who’s Harry Crumb, a film featuring John Candy playing a slums private detective.
The speech by John Cleese (Monty Python) held at his colleague’s (Graham Chapman) funeral.
The deadlines joke in the world (Monty Python, too).
Mister Bean.
Always look on the bright side of life (liedje uit Monty Python, Life of Brian).
Gummbah, Dutch cartoonist.
