Just a few options off the top of my head:
1. Email everyone I've done work for in the past 5 years, promising all of my time on Mondays for the next year to the highest bidder by 2:00 p.m.
2. Same as #1, but instead of the highest bid, the first $10,000.
3. Same as #2, but $1,000. I will accept all checks received in the next 2 hours. What they will get: free use of my next web service for life.
4. Tell my employer that unless he cuts me a bonus check for $10,000 in the next 2 hours, I quit.
5. Write a one page book, "How I Lost 50 Pounds in 9 Months." Make as many photocopies as possible. Put on a pair of pants twice my size and sell the one page books for a buck a piece in front of McDonald's or the food court at lunch time. (I weigh 150 pounds.)
In all 5 cases, I leverage assets (goodwill & good health) I've already earned in much more than 2 hours.
The $5? For the lunch I eat while my "assets" (hopefully) earn.
