This happened to me one Halloween. Back in the day (close to 20 years ago) when I was in really good shape, I went as pro wrestler Randy "Macho Man" Savage. Same height, same weight, same age, looked like him, could do the voice, the whole nine yards. I even got asked for autographs!
BTW, rintense, you do a good Sarah Palin! Hope you have at least another four years to employ this!
