umm...thanks?

Have you ever been told that you look like somebody famous? Well there are 2 or 3 people that I get occasionally, and all of them are completely different. And 2 of them in my opinion are not very complementary. So why would you tell somebody that they look like somebody if that is obviously not a compliment? Thanks. Now my day is ruined. I need a carton of Blue Bell and a spoon.
