Season 4 is one of my personal favorites, containing many of what I consider to be the show's all-time best episodes. We get a deeper look into the Laverne/Lenny relationship in 'Lenny's Crush,' and some pure, fun physical comedy in 'Supermarket Sweep' and 'The Robbery.' Plus, we get to see Shirley take on the hilarious role of stripper Roxy LaTour... so much comedic gold to be had in this stellar season.
