yes I do, Oliver, but a few pointers...
a; its his hand, not his knee. (biology lessons, these two body parts are quite far apart... unless you have your hand on your lap.)
b; he no longer goes to NPF
c; it is very imature to take the pi55 out of someone that has a PHYSICAL deformaty like that. but then again, i guess your the type that goes up to people in wheelchairs and points and laughs, yeah?
d; i forgot, its also his spine, as well as his hand...
shame on you
