The Dali Trick...

Apparently, when he was at the height of his fame, Salvador would take his friends out for a meal and when the bill arrived, he'd ask for a pen, flip the bill over, doodle for a few seconds and sign it. No matter what size the bill was, a signed Dali sketch - even one that only took 30 seconds - was worth far more!

Unfortunately, the good people at the Eastern Seaboard weren't quite as accommodating. But we live in hope...
