While not a phobia, I get oddly grossed out when peeling a head of lettuce...I have no idea why. It's not like I think lettuce is disgusting or anything...but when I'm making a sandwich & go to get some lettuce, I end up with a look on my face as if I'm peeling the skin off of someone's actual head or something...I don't remember ever being molested with lettuce or anything that would make me dislike it nor have I heard anyone with anything even remotely similar...Hmmmm...
