"Wet Hot Demonic Summer" is the second season premiere of the American animated television series Ugly Americans, and the fifteenth overall episode of the series. It originally aired on Comedy Central in the United States on June 30, 2011. In the episode, Leonard Powers is about to retire as the Wizard of Social Services and give the job to his apprentice, Lionel, whom he abandoned fifty years prior. Meanwhile, Twayne Boneraper and Callie Maggotbone must infiltrate the compound where the wizards hold the initiation ritual, but their complicated strategy involves building a summer camp with Mark Lilly as the head counselor.
The episode was written by Daniel Powell and directed by Aaron Augenblick. Powell was inspired to write the episode after reading a critic's review of the series; the critic referred to Leonard as having "omnipotence", which spurred an idea involving the character having to take responsibility. "Wet Hot Demonic Summer" parodies the Harry Potter series, particularly the character design of Lionel.
