At the end of every victory, coaches in Football teams usually get what's called the Game Ball. It's a ball that was used during the game and commemorates the victory. They coaches usually give the game ball to a player, group of players, or coach that performed particularly well during the game.
Sometimes, however, it happens for gross and bizarre reasons too. Wes Welker, wide receiver for the New England Patriots said in an interview that teammate Larry Izzo once had to make an emergency #2 and couldn't get to a bathroom. So he took a dump in the sidelines. What's more, nobody found out at the time. For this, he got the game ball.
Apparently this wasn't a point of shame for the player. Welker said that Izzo would be upset if he tried to claim that the poop didn't happen. He even claimed that the game ball was his most prized possession and he even has Super Bowl rings!
