LPT: If you do something embarrassing, be the first person to make a joke about it. Humiliating yourself is easier to handle than being humiliated by somebody else. Plus, it's a lot more fun that way!

For example, let's say I walked up on a stage to get my diploma during graduation and I tripped and fell. Instead of sheepishly getting back up, grabbing my diploma and running off, I might stand back off, dust my shoulder off and take a deep bow. If you own up to your embarrassment, you'll feel better, people will be more forgiving, and you'll feel much more positive about the experience as a whole! :)
