Lorenzo is really the Devil who takes the form of an infomercial host who promises that he can teach anyone how to play guitar in "Permanent Record Wrecker".

Roger buys the instructional DVD in order to show up a coffee shop musician that he wagers he can best after only a week of guitar training. But when he smashes his television in frustration at not being able to play fast enough, the host Lorenzo comes to life and reveals himself as the devil and makes Roger a deal to win his wager. At the duel, Roger outshines his rival, but cons him into taking his place in Hell by offering to let him keep playing.

Lorenzo is voiced by Stanley Tucci.
