My favorite comfort show is Bob's Burgers!! And I was so happy to see that multiple people on this thread feel the same!
I seriously watch this show whenever I feel sad and it picks me up because almost every episode has a "feel good" moral at the end. Have you guys seen the episode "Sea Me Now"? When Teddy fixes up a boat to impress his ex-wife and he sails past the diner where she works? But she doesn't notice him so he turns the boat around to pass by her again. And then he crashes into the dock TWICE, and she (and a whole crowd of people) definitely notice him then.

This episode stuck with me because I watched it when I was going through a tough time in real life and the message was relevant to me. (You don't have to do well in life to show off to your exes! You should just do well for yourself.)
I just love how each character is quirky in their own way and the recurring theme of the show is to love yourself - it's ok if you don't fit a mold, and nobody fits in all the time.
I also saw the Bob's Burgers movie when it came out a few weeks ago and it was amazing!
