Sometimes the Rot can work to someone's advantage. For example, Jane Krakowski's teen Crotch Rot let her play a drug-smoking victim of incest FOR LAUGHS in National Lampoon's Vacation. Any clean 15-year-old actress would have brought a fatal sense of tragedy to the role.
The perpetually unwashed wonky-faced Kate Moss is riddled with the Rot. You might think that perhaps this is Pete Doherty's fault, but his case of Rot is, oddly, mild, and likely to have been acquired from Kate rather than the other way around. Related fun fact: Believe it or not, Amy Winehouse never had any Crotch Rot.
Christina Ricci's large forehead indicates a genetic predisposition to Crotch Rot, but she could have headed it off before it became a problem. Sadly her tendency to personal filthiness has allowed the condition to flourish.
Jennifer Garner is another of those who is quite obviously unbathed. She clearly wears deodorant over sweat and uses excessive amounts of dry shampoo, and so her Crotch Rot is obviously acquired.
I'm not exactly sure why Tea Leoni has Crotch Rot, but she definitely does. I do know that the problem with Tea Leoni is that she looks like a wall (as in, she has very flat features) and her teeth are quite rodenty. This indicates to me that her Crotch Rot may well be a genetic condition rather than something she acquired--"good" Crotch Rot, if you will.
The origin of Jennifer Love Hewitt's Crotch Rot are harder to pin down. I think in her case it's the general muscle wastage evident in her sloped shoulders, plus her lack of chin. Actually, given the chin thing, whichs she shares with Eliza Dushku, I'm thinking perhaps their Crotch Rot was a condition that originated in utero and continued through a combination of both genetics and environment.
Eliza Dushku first came to my attention in Buffy the Vampire Slayer, where her erratic body movements akin to St Vitus Dance first clued me in to her diseased crotch. But I could have equally pointed out that even when she is clean she looks like she needs a shower. I hope she has a ready supply of Balance Activ.
After Helena Bonham Carter, the next in line to the Queen of Crotch Rot throne is Juliette Lewis. She is shown here in Cape Fear, where she was so slow she actually deserved to die. With Juliette, I believe the problem is her vaguely crossed eyes, her mouth breathing, and her uncoordinated movements, all of which could be caused by a raging infection of some sort.
Let's start with Helena Bonham Carter, aka Queen of Crotch Rot. I think her lack of upper lip bow and perpetually nasty hair are the primary Crotch Rot indicators, but it's hard to be sure. I have a friend who assures me that she is fresh as a daisy. He is wrong.
