When a guy you work with hooks you up and saves you about a week of work, grief and aggravation by bringing home a bit of code that you've been beating yourself up over for a week, you don't say "Thanks".
You hook 'em up with one of these:
Tomorrow, I shall thank a guy I work with for kicking ass.
(and die a little inside when I give it away)
Moral: Always thank your coders.
