A couple of Canadian Football old-timers with a long history of hatred started throwing down at an alumni event recently.They're 2 guys you've probably never heard of. 73-year-old Joe Kapp was a quarterback for the British Columbia Lions. 74-year-old Angelo Mosca was a defensive lineman for the Hamilton Tiger-Cats. They've had a feud for almost 50 years. It started back in 1963 with a controversial hit Mosca had on Kapp's running back. Well apparently Kapp wanted to get over the whole thing but Mosca wasn't ready to. The funniest part of the video is the audience who finds it all hysterical until and old guy gets knocked down.
