Family Guy (1999) - 2x20 - Wasted Talent

When the local brewery has a contest offering tours of the plant, Peter and his friends go on a drinking binge trying to find the winning beer can. Through a stroke of dumb luck, Peter and Brian actually find one of the winning "scrolls". In a Willy Wonka homage, Peter and Brian start the tour, but are quickly kicked out after breaking the rules.

Meanwhile, Lois's students have a big piano recital/competition coming up - and Lois is praying one of her students wins. She thinks she's got a lock on it when she signs a new student, Ling, a piano prodigy. However, in her enthusiasm, Lois works Ling too hard and she drops out! In an odd twist, Peter - in a drunken stupor over being booted from the contest - sits down at the piano and plays brilliantly! Lois is thrilled and keeps Peter drunk long enough to win the piano recital.
