   Summary

   When Cartman starts hooking up with the Imaginationland version of Kyle, everyone just rolls with it. But the real Kyle, naturally, has some concerns. Namely, how it's affecting his feelings towards Cartman. But when he finds out that his horny doppleganger would like to experience a life outside of Cartman's bedroom, they decide to do a Prince and the Pauper style swap.

   But will Cartman find out? And would it be the worst thing in the world if he does?
