Funniest sound or expression?

What's the funniest thing you've said or noise you've made (guys) or made or noise/words you've made a guy say (ladies) from ballbusting?
I haven't been hit good and hard many times, so for me it was words. I blurted out "Not my baggy!" when she went to squeeze them. I didn't plan to say it, it just came out and she got a good laugh out of it.

Links to funny sounds are also welcome.
