Season 1, Episode 6: "Wine and Roses"
The first season of Schitt's Creek isn't home to what most fans will call the "best episodes": it's clearly a show that's still finding its way, and the comedy is a little sharper and meaner than it is in later seasons. But this episode is an early gem. Moira is approached to do a commercial for fruit wine and promptly melts down, which gives us a surprisingly sweet insight into the Roses' marriage. Meanwhile, David thinks he's dying but realizes he's actually having a panic attack, and he accompanies Alexis to a superawkward yoga class to try to relax. Bonus: a full-fledged introduction to Catherine O'Hara's deliciously daffy accent-shifting for Moira.
