I'd rather be full of shit

I was out for sup kambing with Leonard the other day.

And I brought up the subject of being the butt of skinny jokes.

So I said, "I know why I'm still skinny. It's because I shit everyday. So my body doesn't absorb anything important enough for me to get fat."

With all seriousness, he looked at me and asked, "So you're saying you'd rather be full of shit is it?"
