what are some ways you use to keep your anger in control and not shout at kids?

i have in a very funny way many times laughed out loud when i am angry. actually, when my daughter does something, i sit down on the floor on her level, look at her and ask her what she did. the answers she gives or the faces she makes are too funny to not laugh. at toddler age, she does not do soemthing so bad that i have to lose my cool for it :)
