Charlie thinks Mac's mom is holding his mom hostage so the gang installs spy cameras in their house to monitor what's going on. What they end up discovering is the moms are quite entertaining once Dennis makes some quick edits and adds a laugh track to the surveillance footage. Dee wants in on the new hit show and Frank becomes obsessed with banging Charlie's mom now that he's seen her on TV.
