Vince Vaughn, who previously hosted fifteen years ago in 1998, delivered a refreshingly unconventional monologue, but at times seemed a bit stiff. Musical guest Miguel performed "Adorn" and "How Many Drinks?"

Some highlights...

Cold open—Senators Joe Manchin (Jason Sudeikis) and Patrick Toomey (Bill Hader) proudly present their ineffective gun-control bill. ("We were able to ban the sale of AK-47s from coin-operated vending machines, and to outlaw Papa John's promotion, "Buy two medium pizzas, get a free gun" ... except on weekends and during the Superbowl. Also, this probably goes without saying, but none of these restrictions apply in Florida...")

The monologue—Vaughn ventures into the studio audience with instructions for proper show-watching etiquette.

A new rockumentary looks back at Britain's angriest punk musician (Fred Armisen), who had a soft spot for Margaret Thatcher. (Also featuring Sex Pistols guitarist Steve Jones).

Brad Paisley (Jason Sudeikis) and LL Cool J (Kenan Thompson) drop by Weekend Update to discuss their controversial song "Accidental Racist." ("We know the song's not perfect. It's not even good...")

Barfly Kate McKinnon (who picked up Louis C.K. in November) hooks up with wasabi pea tester Vince Vaughn at last call.

Also: Al Pacino (Bill Hader) goes too far with his HBO accused-murderer portrayals—taking on the roles of Amanda Knox, both Menendez brothers, and Dr. Conrad Murray, in blackface; the woman allegedly raised by monkeys (Kate McKinnon) drops by weekend update; the Weather Channel debuts its first soap opera, Stormy Skies; and NBC looks back at the rejected lyrics to its NBA theme song, "Roundball Rock," by John Tesh.

NEXT, on May 4: Zach Galifianakis with musical guest Of Monsters and Men.
