Apologies. I made two mistakes there. First, it's Batman Forever, not Returns, and second, although TGwtG participated in the riff, I now see that Jonah wasn't one of the riffers. Oops. Still, do check it out anyway. It's one of the better iRiffs out there.

Regarding Jonah, check out his (and a few others from That Guy with the Glasses) RiffTrax of Batman Returns. It was so well done and hilarious that it changed my opinion of iRiffs completely. Hated 'em before hearing that one, but now, due to my slightly opened mind, I've discovered such gems as ICWXP.
