This is a tough assignment. I think I’ll go with 'Halloween Surprise', the episode of "Parks and Rec" where Ben proposes to Leslie. Mostly because it was the episode that made those two characters as happy as they had ever been, to that point, which is a good feeling for a writer.

But also because the main plot centered around Jerry having a heart attack, and then farting, which allowed us to coin the phrase “art Attack.”
