A very funny and pregnant Tina Fey returned to 'Saturday Night Live' this weekend for another round of hosting duties.

As expected, the episode poked fun at the recent death of Osama bin Laden. The night also featured sketches written around Fey's pregnancy, a hilarious spoof of Bravo's new reality series 'Pregnant in Heels' and, of course, the return of Fey as Sarah Palin.

Still, the night wasn't entirely about Palin. In a hilarious surprise, singer Michael Bolton appeared in this week's Digital Short, in which he expressed his love for 'Pirates of the Caribbean' character Capt. Jack Sparrow.
