This joke is funny because lycanthropy is a mental disorder in which the patient believes that he's a werewolf, so now that he's cured he's "over the moon" (a phrase meaning to be extremely happy) and also "𝒐𝒗𝒆𝒓 the moon" (meaning that he no longer cares about it). #Werewolf https://t.co/n5AYo5hJxA
