Ecto Cooler (S05E08)

In his quest to impress Sperg and gain some coolness, Billy unwittingly releases an ectoplasmic spirit from his mouth. This ghost turns out to be the famed nineteenth-century British poet, Lord Byron, who attempts to show Billy that true coolness lies in the power of poetry rather than in brute strength. When Billy uses a verse to mock Sperg’s mother, a duel is promptly arranged. Despite teaming up with Byron in the ensuing fight against Sperg and his crew, they suffer a significant defeat. Before vanishing, Byron reveals to Billy that he has mastered the art of coolness.
