The Simpsons (1989)

S13E3 Homer the Moe

Feeling down, Moe opts to go back to bartending school for some self-reflection. While there, he reconnects with a former instructor who encourages him to enhance his bar, potentially lifting his spirits. Inspired, Moe revamps his establishment into a stylish nightclub, but this transformation doesn't please his loyal patrons Homer, Lenny, Carl, and Barney.
