I think he was joking more than anything, but the play before Favre got hurt, Randy was running a go route and Favre threw it up there, the defender interfered with Moss(and got the PI) and Moss stopped running and didn't even attempt to catch the ball. It would've been an easy TD and Moss would've walked in had he tried. Thus Favre and the Vikes would've walked off the field and Brett wouldn't have gotten hurt. lol.
