I **hate** it when they "jokingly" ask if you forgot your name. Makes me all sorts of mad. Of course I didn't forget, you nobber. I always make the point of saying that I didn't forget but that I have a stammer, which makes saying my own name sometimes really hard. I like how they get uncomfortable at that point. Cruel - but it'll stop them ever making that quip again to someone, so I take it as a win.
