doctors...my favorite
I, too, LOVE doctor tickle stories....
The abdomen thing always made me flinch and have to fight it....that's my worst spot...my stomach goes in automatically and I feel like, "man if this goes on much longer I'm not going to be able to take it....".....but here are some better stories...
My ex-gf had "fallen arches" as she called them - I think it's basically the same as flat feet, and had some pain in them, so had to go to the doctor for that. The doctor, for some reason, had to draw lines down her entire foot with a pen to make some measurements. She said it tickled an incredible amount and it took all her will power not to pull away. She gripped onto the table where she was lying with both hands, and made lots of faces. Her mom (I love this part) was sitting in the office with them, and said, "She's really ticklish."
At another visit with a different doctor - I forget if this was for the arches or something else - the doctor was checking her alignment and posture. She was standing up, and he put his hands on her hips and and pressed in. He said, "I hope you're not ticklish", and she said, fretfully, "I am..." She said it tickled like crazy and she wanted to move away but knew she had to stay still for the examination.
