When I was ruling the gridiron, we ran a drill that we called "Duck Hunt" Coach would lob up a wobbly pass to a receiver coming across the middle. The receiver would jump up to make the catch, and it was our job to knock his block off so hard that he wouldn't come down with it. I always jumped up and smashed my helmet right into the receiver's helmet to ring his bell just like coach said. As he was lying on the ground in pain, I got in his face and said "Ding Dong, bitch".
