It’s funny about Venus of Willendorf. I always describe myself as having her body shape, and I’m not being self-deprecating. I’m a goddess 
So I don’t hate my massive hips and butt, nor even my belly, though I am dieting and exercising in an attempt to get them more down to Venus de Milo proportions. (I’m not cutting my arms off, though!) I’d say the ugliest part of my body would definitely be toe related - the little toe on my right foot sticks out too far, and is therefore curled up and constantly bunioned from shoes. And I wear wide shoes too!
Feh. MY feet have fungus under every toenail, the weird lumpy ridged big toe nails from ingrown nail surgery, athlete’s foot between the toes, and dry cracked skin between the calluses on the soles. I have a tuft of hair growing on each big toe, and on top of my arches, and nowhere else on my feet.
My nose. I have a bump on it and it’s longish and of course it turns reddish if i touch it, sneeze, wash my face, go outside etc. I’d never have plastic surgery on it though.
Me too. I can’t fully describe why, but they’re too lumpy, while the rest of my legs are not. An unattractive scar dons each kneecap, to boot.
The fact that I have more weight on the bones than I should speaks for itself 
That, and my bum. I hate my bum.
How about, oh… everything below the boobs.
Ugliest part of my body: my body.
First, I have hideous toes. The two toes next to the big toe, on both feet, are conjoined. They disgust me. Second, I have the worst butt ever. It manages to be both wide and flat. Third, I have bad teeth. I never grin; I only smile.
It would have to be the area between, say, where my chest ends and where my legs start. I am pretty athletic and generally in shape… I have a decently muscled upper body, my legs are what we’d call “soccer legs”… and I have a nice little spare tire around the middle. Bleh. I can run a five minute mile and I still have freaking love handles :mad:
My tummy. Two kids and some extra poundage = blech. There’s nothing else on my body I truly can’t stand.
While my body is no treat to look at, my right breast is definitely the ugliest bit. I had a papilloma removed from inside the nipple some years ago, and the nipple is still scarred and a bit misshapen. The scar is still a bit tender, too, and it’s hard to wear a bra.
Runner up are my legs…very dry and swollen, and I have a tendency to get cellulitis (a skin infection, NOT cellulite) on them. The cellulitis is really and truly ugly.
I have always been particularly ashamed of the third duodenal villus on the left.
My forehead. It’s too high, and it frustrates me because I can’t pull my hair completely back because of it. It’s too severe looking.
My nose, not because it is big, but because of the shape. It has the Roman curve. I have learned to live with it, though.
My stomach. It’s fat. Not hideously so, but you could definitely call it a pot-belly.
Then again, even at my very thinnest and fittest, my tummy was never flat. So I guess it’s just the way I am.
But it’s still ugly.
I’m jealous of you people who say that the worst thing on your body is your freaking TOE! Or your eyebrow! I wish my toe was the worst part of my body.
For me:
Boobs - too small. I don’t even want big boobs. I just want normal sized boobs. I’d kill for a B-cup.
Knees - they’re so knobby its sick. I never wear shorts, ever. The only time you’ll see my whole leg is if I am in a swimming suit.
Abdomen - I’ve gained about 15 lbs this year and its ALL went to my stomach and love handles. Now I’m starting to get small stretch marks that are just gonna piss me off. And the boobs still didnt grow. And I’ve got gut hangover and its gross.
Eh… I’d do 'er.
Bite your tongue! There’s nothing ugly about me. In fact, just today I had a brand, spanking new widow who has been a friend for over 30 years tell me that she has a crush on me.
I told her that I was into ravishing not crushes. Unfortunately my kit of ravishing tools is currently out of order. She cried.
Thighs. Hate 'em. Always hated 'em. Even when the rest of me was fit & trim, my thighs have always been too short and too fat.

This answer is so close to mine that I shall just say: ditto.
Thanks, astro. <embarrassing smoochie noises> I needed to hear that.
