Oh, Mama!

Pregnancy can be miraculous, stressful, exhausting -- and, as Tina Fey reminds us, funny. In a raunchy Mother's Day duet on Saturday Night Live last May, a six-months-pregnant Fey and an even-more-pregnant Maya Rudolph sang to their unborn babies about love... and how they were proof that their moms had been "doin' it!" For the finale, stagehands rolled out a sonogram machine so that Fey and Rudolph could sing a duet with their fetuses, which looked suspiciously like Kristen Wiig and Kenan Thompson. Wrong? Probably. Funny? Oh yes.
