The Prisoner of Benda
Look. This one gets messy. I don't know what to tell you.
Everybody switches minds with everybody! Fry is Zoidberg! Leela is the Professor! The Professor is a daredevil robot called "Nonchalanto!" Romances are tested and hearts are broken and mathematics happen.
We also talk about DVD audio commentaries (for things other than Futurama), invent a TV show that's just 3 shows smashed together, and question the future NBA.
Ben switches bodies with The Rock. Mike siwtches bodies with his dog.
