State du Moi.

I love ending a work email with "hope this helps!"; in only 3 short words you've conveyed the sense of absolution of any real responsibility, a sense that you really busted your hump trying to find an answer (you did not), if anything good DOES come out of your answer of course you'll expect full credit, but most of all it's a nice way of saying "now don't ever fucking bother me with this bullshit again".
