Tina Fey and Maya Rudolph Mother's Day Monologue (Season 36, 2011)
It doesn't quite get better than a Mother's Day monologue with Maya Rudolph and Tina Fey singing about how their pregnancies prove that they've been laid before. Fey's technically the host here, but bringing her pal definitely made the monologue all that better. Plus, they actually both sound quite lovely even while singing about being horny, wild mamas! And Kristen Wiig and Kenan Thompson as their in-utero babies? I am deceased. (Also check out Fey's cameo in Emma Thompson's recent Mother's Day tribute!)
