Before Brett Favre became the poster boy for "just playing like a kid out there," he had to earn the reputation both on and off the field. In this mid-90's clip, Favre and Don Beebe wear each others' jerseys (while Frank Winters stands silently in the back) and pester then-Packers head coach Mike Holmgren for candy he doesn't have.
It's astounding to see how comparatively small Frank Winters was. Can you imagine a contemporary offensive lineman not being immediately recognized by his head coach as a football player?
