Lester Young was a bookie.
In 1944, Lester helped a man named Ethan Snider in casting bets for horse races, and Ethan always won. Eventually, Lester felt disturbed by Ethan and ran away from him. He was later confronted by Eliot Ness and Dean Winchester who demanded to know about Ethan. Using the "good cop, bad cop" tactic, the men forced Lester into revealing that Ethan frequented The Early Bird, a dive bar.
