I can do the cherry stem thing, too. Fun party trick. Never failed to get comments from my wife's friends at parties. Funny thing, she was always the one to bring up my "special talent." When ever she got a drink with a cherry in it she would make some kind of a statement about me taking her "cherry." Her friend would make crude joke about it, but then my wife would say, "That was great, but you should see what he can do with it now" and then hand me the cherry. After I spit out the knotted stem her girl friends would do everything from giggle to flat out ask her if they could barrow me sometime.
Another talent (non-sexual) is that I can write a mirror image. I can take a pen in each hand, place both in the center of a page, and whatever I write with my right hand I can write a mirrored image with my left hand at the same time. The left hand is writting the letters facing backwards and going from right ot left. A talent that has absolutely no value, but impressive as hell at a party!
