Other athletes who have hosted SNL-- Peyton Manning, Michael Jordan, Tom Brady, Nancy Kerrigan, Jonny Moseley, Wayne Gretzky, and Lebron James to name a few--have had mixed luck.(but this Manning "United Way" commercial is great). And the musical guest is Lil Wayne, one of Phelps's favorite musicians. People writes, "No word yet on whether he will be wearing a Speedo."
