It wouldn't be fair to read too much into this unintentionally hilarious image, but we are dealing with the master of tenuous connections, so I think for humorous effect I'll interpret this is evidence of faux-libertarian treachery backed by ACORN, the RIAA, Hagar the Horrible and the bass player from Styx.
