Hart High graduate Joe Kapp, famed college, NFL and CFL quarterback, and Angelo Mosca, who played for the Hamilton Tiger-Cats of the CFL, exchanged blows and heated words during the CFL Alumni Legends Luncheon in Vancouver, Canada, on Friday, two days before the Grey Cup.

Kapp, 73, offered Mosca a flower when the two players were announced before the luncheon crowd. Mosca can be heard saying in the video on YouTube, “Shove it up your a__.”

Mosca, also 73, then takes a swing at Kapp with his cane. Kapp avoids Mosca’s cane and hits Mosca in the head, knocking him off the stage.

Kapp played for the British Columbia Lions in the CFL in addition to quarterbacking the Minnesota Vikings in the NFL, California Golden Bears college team and the Hart High School football team. He graduated from Hart in 1958.

Mosca played defensive tackle for the Tiger-Cats and was a professional wrestler.
