Paul Rudd is hosting "Saturday Night Live" for the third time, but it's musical guest One Direction that caused the actor to have a pillow-biting fit in one of the new promos for this week's show.
Rudd, who at 44 still looks like he's young enough to be in a boy band, loses it after "SNL" cast member Vanessa Bayer gets giddy herself over the prospect of seeing the lads "right here in this building where we can talk to them."
"Wait. The band?" Rudd asks. "The band with the hot British guys? Niall, Harry, Louis, Zayn and Liam?" He then snatches the pillow from Bayer's hands and screams into it. "Oh my god, oh my god, oh my god, oh my god, oh my god ... I am fangirling!" he yells before running off camera.
Rudd is clean-shaven now, but the mustache and long hair he sports as newsman Brian Fantana will be back on the big screen later this month when "Anchorman 2: The Legend Continues" opens in theaters.
