Listen to One Direction on iHeartRadio

One Direction pandemonium is set to take over "Saturday Night Live."  The British boy band is the musical guest on this weekend's episode, and in a new promo host Paul Rudd is looking for a piece of the action.  

It continues with more unsuccessful attempts by the "Anchorman 2" actor, who is hosting the NBC sketch show for a third time.  In earlier promos, Paul and cast member Vanessa Bayer let out their excitement over One Direction's arrival by hyperventilating and screaming into pillows. 

This weekend will be One Direction's second visit to Studio 8H.  They've been busy touring in promotion of their latest album Midnight Memories, which came out last week and debuted at number one with 546,000 copies sold.
