I visit certain message boards from time to time, including one called vdrums.com, a site dedicated to electronic drumming. While there's a lot of useful info there and a bunch of friendly and helpful folks, there are also some entertaining end-of-message signatures that folks use. Here are a few examples:

One that's stuck in my mind, from a statistician (and presumably a gamer): "It's not the winning, it's the taking apart that counts".
And one one of your SciBlings used up until recently:
"He used... sarcasm. He knew all the tricks, dramatic irony, metaphor, bathos, puns, parody, litotes and... satire. He was vicious."
Wait a minute, Luigi Vercotti has a blog here?
