The Bay Area Democrats and 'A Texas Republican For Ethical Reform" are apparently joining together to protest Tom DeLay's keynote speech at the NRA convention this weekend in Houston. The flyer (.pdf file) points out strongly that this is not a protest of the NRA, just DeLay.
So if you don't have anything better to do Saturday night, mosey on down there and just yell, "JERK" over and over again and see if Tom hears you.
