Hot or cold...

According to the Denny Crane school of rating women the only two planes upon which we decide whether a female is - for the lack of a less colloquial phrase - hot or not are whether she IS de facto female and whether she has a pulse.

DC may seem somewhat broader in defining horizontal illegibility than our purposes require so he is not going to help us with the conundrum that is Katie Perry.  

Kissing another hot girl obviously increases the attractiveness of a girl, but we are not so sure that is enough. Cameoing in her bf''s gym class music video she isn't half bad, but in her own 'hot and cold' video she is super sexy. We think we should poll it: Katie Perry - hot or not?
