Stephen Colbert called out Anderson Cooper for ripping off his big board with CNN’s RidicuList a couple weeks ago, and the silver fox finally took the bait. Last night, he added Colbert himself to the RidicuList, lobbing bombs back in Colbert’s direction with a whole segment dedicated to him. Cooper handles the sparring well, laying down some pretty good jokes of his own (that Ben and Jerry’s bit in particular is pretty great). What’s next for this faux-feud? The ball’s in Colbert’s court now, so we’ll have to wait and see. Hopefully something involving more large charts and graphs, which are automatically at least somewhat funny.
