OOOhhhh yes,love that one.Also when she then,just at the crucial point of the fight,shouts:" Sheldon!Watch out!" when he´s looking in the right direction anyway,but because she says that,looks in a different direction and gets whacked over the head.Or,other possibility,she shrieks:"No,no!!!!" and hangs herself all over him,thereby neatly forestalling any chance he might have had of getting a fist in.
Also nice is,have you noticed that,when in a crucial situation,and somebody calls out:"Sheldon!Watch out!" the hero always knows exactly in which direction to look and also knows straight away whether to lunge or duck.
Except when fighting with some guy and the girl is in the background,then he gets dotted on the head,as beforementioned.
AND: When fighting with the hero,the baddies will always take turns beating up the hero.Noone ever comes from behind or trips him up or something.They all stay back till the hero has knocked the first one out,then queue up for the next one and so on.
AND: When the hero has managed to get himself caught,the baddie will always conveniently leave the room,or do something else,or turn his back,or talk,so that the hero has a chance of escaping.They will never shoot him straight away,even if there is a bomb ticking next door which is due to explode at any minute.
It´s still magic even if you know how it´s done.
