- Give a short spiel imploring the crowd to donate to a Worthy Charity, just drop a few coins in the hat as you leave. (Make sure you do in fact make a donation to some local charity - and be seen doing it.) Keep the difference.
- If the greater plot involves Robin Hood and Prince John, deliver yourself of a wink-wink nudge-nudge "not-political" commentary on how King Richard the Lion-Hearted did such a good job as king, nobody else can measure up ... even if they tried, or were in fact trying. And how Robin Hood is behaving as nobles ought, once you scratch below the surface of his bad press.
- Start a riot with an inflammatory speech.
- One-on-one, explain how a rich person can make a bet with friends, that XYZ (one option of many) will NOT happen. Their friend bets that it WILL happen. More likely than not, your friend will owe you $$$. Repeat many times, keeping track of your bets. If you cover all the options, you can make it so the other bettors pay off your one loss and you keep the difference. If implemented, this plan will make you a richer friend when you come back to town; that is the time to call in the favor with him.
- Write a horrible "social protest" song to use as your encore. Because that's how it usually works out. (Cast Protection from Flying Tomatoes &c on yourself before the encore.)
