Like many offices, the Ravens' locker room on a Friday is a loose, laid-back place.
The room reverberated with the sound of the jukebox playing Sir Charles Jones' "Friday," with many players singing along.
Finally, wide receiver Steve Smith Sr. decided he'd had enough.
"I'm all Friday'd out, man," he said, striding over to the machine to put on Jay-Z's "U Don't Know."
