The Lisp Machine keyboard had dedicated open and close parenthesis keys, so you could hold a hefty bag of nitrous oxide in your other hand while you typed s-expressions.

Wait, what are you doing with that nitrous oxoide? Should I start worrying?

Well, when you're done with the nitrous oxide, just toss whatever you wrote into the obfuscated code contest.

There's a reason the paren keys had really fast auto-repeat!
