Least? I was actually always turn on by Slappy... Although, I was a kid back then... and even back when I was attracted to older, mature women. So... Yah, I had to make her look at least moderately attractive.
To me she always had that image of a woman in her late 40's who smells of alcohol and cigarettes and has a "fuck everything I'm old!" kinda mentality. Don't get me wrong I LOVE her ballsy badass nature...it just never translated to "sexy" for me. :P
(But I must add that here she is the definition of sexy so you do your job very well. ;)
