Here's one to take to the Portland streets next time:

"I say 'Black Bloc' You say 'Dumb F*cks!'
"Black Bloc!"
"Dumb F*cks!"
"Black Bloc!"
"Dumb F*cks!"

[please note I intend zero racial component in the above... "black bloc" is the name of  the wanna-be-anarchist sector of these marches --- comprised almost exclusively of privileged white discontents, mind you ---  that is under the illusion that an effective appeal to the public constitutes giving the finger to reporters, yelling "F*ck [insert whatever]!" and playing what they jokingly and affectionately refer to as "Smashie-Smashie." Great tactics, fellas!  :/ ]
