How can I mentally control embarrassment?

What can I think to myself to be able to not be embarrassed?

Everybody that knows me well will say that I have an upbeat, comical personality. The reason I don't get embarrassed is because I make every mistake of mine into a joke... it fits my personality. I laugh about it with everyone. If you cover up the fact whatever you did was stupid, it won't be so bad. I do also think before I do things. I have a feeling this saves me a lot of 'embarrassment'. Learn to laugh at yourself and you should be fine.
