lock trick
i played football at caltech for several years. each year i got a new locker. they never changed the combinations of the locks. to look cool i'd dial my combination before practice and after practice i'd just yank the lock open. one time there was this guy i didn't know sitting there tying his shoes. let's call him mark. mark looks surprised by the lock trick. it's a gift i say. mark chuckles nervously and says just don't do that to my locker. and of course mark's locker used to be my locker. and i remember the combination. so i sigh. dial it. look at mark. and yank his lock. mark was still trying to tie his shoes when i left for the shower.
