I guess most people dont remember this.  But this happened.  Satoshi asked Mike Hearn to send him bitcoin as a test, and promised to send them back.

Mike sent 32.51 BTC

Satoshi sent back 32.51 + 50 BTC = 82.51 BTC

Some time after that, Mike became disillusioned with bitcon and rage quit the project.

82.51 BTC (worth around $5 million) are still there
