Some kids are just born funny- I am convinced of it. My son is hysterical and he's not trying to be funny, it's just the way he sees the world. Some of his gems:

A friend stole food off his plate and he responds with "Stop or I'm gonna fork you!" You can imagine exactly what that sounded like at 3

When he is sick he insists that he has "to go blah"

At 2 we were driving on a beautiful day with the windows rolled down. Pulled up to a stop light and saw the people playing tennis at the corner. Just as the light turns green and I step on the gas (and his inborn sense of comedic timing perfectly tuned) he yells "asshole!" I know I should not have laughed, but where the heck did a 2 yr old get the idea to do that?! It's not something he ever got from me or hubby... our 8 yr old has never uttered a curse word much less yelled it out the window of a moving vehicle at people... yes, some people are just born that way
