the other day i found out that my mother & my 2 aunts got their feet tickled for punishment when they were in their teens...one incident mom got drunk & crashed the car into garage...so they gave her a choice of being grounded for a year from everything or get her feet tickled for half an hour....well her mother and father sat on her laying face down while her sisters tickled her feet relentlessly for 30 minutes....mom said it was horrible that it was the worst she had ever been tickled.....i know where i get my ticklish feet from now!
