Tom Brady Loved Watching Bill Belichick Tell Vikings Star To 'Shut The F*ck Up!'

Tom Brady couldn't help but laugh his ass off at seeing Bill Belichick cuss out Minnesota's star wide receiver on Sunday ... saying, "That was pretty funny."

During the Pats win over the Vikings ... Adam Thielen flipped out at Belichick for challenging a close spot in the 4th quarter -- to which The Hoodie replied, "Shut the f*ck up!"

Brady couldn't help but chuckle at the whole scene ... telling WEEI's "Mut & Callahan" show, "I’ve been on the other end of that a few times in my career."

"Pretty funny. … It’s competitive out there. It’s very feisty and everyone’s emotions are on their sleeves. You say something and there is just an emotional reaction. That was pretty funny.”

Of course ... Tom and Bill can laugh all they want now -- they ended up rollin' the Vikings and look poised to catch the Kareem Hunt-less Chiefs for the top seed in the AFC.

As for Minnesota -- their season's on the verge of crumbling ... but at least Thielen still looks like he's gonna be an All-Pro at the end of the year.
