I always thought if you really want to be a good actor, you've got to be able to fart in public. That, to me, is the most important. If you are so inhibited that you can't fart, I don't mean around your friends, I mean just a fart, out loud somewhere. I don't mean the 'silent creeper', everybody does that. I mean fart out loud! Just that you can do it and not be afraid of it. Humility is very important.
