Do I amuse you? I make you laugh, I'm here to ... amuse you? What do you mean funny, funny how?
I will find you Mr. Hitchens and I will make you laugh. (OK, I concede I now fall into the described “hefty” category, but I could be quite amusing when I was much thinner. Except maybe during my senior in high school skirting anorexia phase. People who are constantly worried about the calories in half a graham cracker or a large apple versus a medium orange have no time for humor.)
