Sure we all have that one episode we claim to say is the worst (Everyone's looking at you, Mare Do Well) but nobody ever seems to say that each season had a worst episode. So I'd like to know what you think is the worst episode or episodes from each season.

I'll start it off: 

Season 1: Griffon the Brush Off, Call of the Cutie, and Owl's Well That Ends Well

Season 2: Dragon Quest and both Royal Wedding episodes

Season 3: Both Crystal Empire episodes, Spike at Your Service, and Just For Sidekicks
