S4 Ep6: Jesus Is Risen (or "Hey, Zeus" if You're Spanish)
Happy Easter! Carmen tells John how Easter is different in Spain. The duo then relates who got more gifts for Christmas before Carmen turns everything into a nightmare as she regales all in the story of the Tooth Fairy in Spain. Spoiler alert: it's a rat. Plus, Easter means spring cleaning which leads John and Carmen to go back in time when John discovers old mix tapes from ex-girlfriends. Of course this leads to Carmen role playing as John's exes. Of course.
