This is old, but still amusing.
That was actually basically the first thing I ever saw that Sarah Silverman did, and I thought it was hilarious. So I looked up some other videos of her stand up and some other comedy bits she’s done, and realized that her entire comedic range consists of looking vaguely innocent and then cursing and saying things that are in bad taste and totally improper to the situation. Which is funny (at least for me), for all of about one video before it gets really old and I wish the comedian had enough of a brain to have some range and variety. So if that is the only clip of Sarah Silverman you’ve ever seen, stop now, while it’s still funny.
