Riker catches an alien "virus" (from a plant) and lays down naked under a shiny blanket for the rest of the episode. Pulaski forces Riker to dream of the most boring and worst segments from season 1 and 2.

Most shows have flashback episodes that feature highlights. TNG had a clip show that showcased the worst segments. It was the most lackluster finale episode of any Star Trek season. And this was even well after Riker "grew the beard".
