"How to have fun with our Republican 'friends' at town halls"
(http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=132x8583393), I humbly suggest this:
Go up to the loudest, most obnoxious one there, and thank him or her PROFUSELY for following the President's plan! Then remind him/her to make CERTAIN they get on camera, show they can show the nation how obnoxiouis these protestors are. When they deny it, look shocked, say "oh..you mean...", then walk away laughing hysterically!
