Will Ferrell dropped in on a Seattle Seahawks Zoom meeting this week ... making fun of new tight end Greg Olsen and showing off his "yoga bod" -- and it was all absolutely hilarious!!
Ferrell and 'Hawks coach Pete Carroll have a friendship that dates back more than a decade (it's a USC connection) ... and to liven up a mundane football talk Thursday -- PC had the comedian call in.
The results?? They were laugh out loud funny ... with Ferrell pretending to be Olsen and firing off jokes left and right.
