This one's from the comedy movie Anchorman: The Legend of Ron Burgundy, which is in my eyes easily the best movie Will Ferrell starred in so far.
The whole movie's great, original and quite hilarious to be honest. (it even co-features and cameo's his ol' buddies from Steve Carell, to Ben Stiller, Luke Wilson, etc..)
It has that distinctive 70s tone and look as well.
Anyways, enjoy this classic clip:
