The Good, the Sad and the Drugly is the seventh episode of Season 20. It first aired on April 19, 2009. The episode was written by Marc Wilmore and directed by Rob Oliver.
Bart volunteers at the Springfield Retirement Castle in order to impress a girl, but this leaves Milhouse (who took the rap for a school prank he and Bart pulled) less than impressed; Lisa becomes depressed when she writes a report on what Springfield will be like 50 years from now, but her medication makes her see everything happy – bright yellow happy faces, that is.
