My Top 10 of MAMA

1. Rashomama (Gooseberry Jam)
2. Flaming Forties
3. Cellmates
4. Supermarket
5. Black Belt Mama
6. Mama Gets a Job
7. Positive Thinking
8. Mama Learns to Drive
9. Cat's Meow
10. Where There's Smoke

Outside the top choice, this is a tough call! Here goes ...
1 (far and away). The Wedding
2. Mama Learns to Drive
3. No Room at the Inn
4. Rashomama
5. A Grave Mistake
6. An Ill Wind
7. The Really Loud Family
8. Cat's Meow
9. Farewell, Frannie
10. Positive Thinking

Reading the Riot Act and Bye Bye, Baby are honorable mention for me. Best Medicine is as well purely because it's Betty White's final appearance.

Very hard to decide but if I had to choose, it might look like this:

1. Rashomama (can't wait to see the uncut version of this classic episode)
2. The Love Letter
3. Positive Thinking
4. The Really Loud Family
5. The Wedding
6. Mama Makes Three
7. Psycho Pheno-Mama (Hilarious guest shot by Liz Torres)
8. Sins of the Mother
9. Mama Gets the Bird
10. No Room in the Inn
