I'll add Natalie Portman, but with an explanation...
I don't see why people go Ga-Ga over her. She's cute, I admit, but she's not the end-all, be-all of womanhood. She's just cute. I've seen better at clubs on a weekly basis than her, so I can't see all the fandamonium.
I've never seen anyone list Carrot-Top in a "hot" thread anyway, but I have to admit that the dude's ripped. I wouldn't tell him he's ugly to his face. Years of looking like that, but with his size, have probably made him quite capable of kicking the ever loving **** out of any one of us.
I saw him once in Pittsburgh just eating his lunch at Station Square (where the only comedy club at the time is/was), and he actually was quite normal. Keeps his hair pulled back and stuff.
Anyway, I agree on Paris Hilton. She's a double-bagger but I'd probably still do my business if the chance arose. The face is where I think she's off.
Same with Sarah Jessica Parker (BTW she's my good buddy's second cousin, which is your useless fact of the week, brought to you by me).
