Australian Atheists Chant "ZZ TOP" At Muslim Counterprotesters

From Tim Blair at the Daily Telegraph (via Legal Insurrection blogread), this is what happened outside an athiest gathering when a group of Muslim counter protesters showed up. The athiests chanted back "Where are the women?" "Bull$h!t!" and "ZZ Top."

ZZ Top? Seriously?

I don't see a resemblance.
