I never answered this question because I can't think of any Columbo character who I resemble. However, my students at school tell me that I look like Drew Carey. Actually, I don't really see a resemblance (other than that we are both fat guys with buzz cuts). But it is something that comes up with every group of kids that I have had, so maybe I'm just in denial.
So...can anybody think of a Columbo character who fits the requirements?
