Neither Jim nor Historian have shoved anything up their asses in anger, at least not to public knowledge. But it does ring a bell, thought I can't quite place who it was. We know The Amazing Atheist shoved bananas up his ass but it wasn't out of anger, and there's that kid who had a video of him having a tantrum and putting a remote control in his ass, but he was famous for it, not before it (and may have been found year later that it was staged?).
Chyat, who is this angry ass-shover we're thinking about?
