Here's one from David Ackerman: Not sure if there is a place readily available in your area, but here's my idea: Come up with a comedy act and perform at open-mic night of a club/bar. A couple questions for me and other potential commenters:What day are you planning on doing this? You might get better ideas if you are willing to do the challenge on a weekend (as you would have more free time), then if you insist on a workday.
