Kirstie Alley: I don't think fat is pretty. If I saw some big fat leopard walking through the jungle, I'd start laughing. Or if I was at the races, I saw some 150-lb. greyhound running against the other lean greyhounds, I'd start laughing too. It doesn't seem very natural. It doesn't look healthy. It doesn't look sleek or stealth. It looks funny. I think that's why people through history laugh at fat people. They're round and funny-looking.
