What? Zippy Hijacked by marauding speech balloon appropriators? This shocking turn of events and more is chronicled in the latest collection of the Zippy the Pinhead daily comic strips, Zippy: Walk a Mile in My Muu-Muu. In the aforementioned storyline, all of the strip's dialogue is usurped by balloons taken directly from old comics like 'Beach Blanket Bingo,' 'Rusty Riley,' 'UFO Comics,' 'Mutt and Jeff,' and 'Steve Roper.' Will Zippy get his voice back? And will he remember being abducted from a Kansas cow-lot by little gray aliens?
