*“Saturday Night Live” featured its former head writer Tina Fey as host this weekend along with a surprise return from cast member Maya Rudolph – both of whom are pregnant.

The situation called for a special Mother’s Day ode to their fetuses as only those ladies can do.

They started off singing slowly and earnestly about how they “couldn’t wait to know” their unborn children. Then the tempo picked up and the two ripped into a raunchy tale of how they got knocked up.

Later in the show, Fey got her Sarah Palin on during a Republican debate skit that also featured the return of Jimmy McMillan from The Rent is Too Damn High Party.
