In the wake of the Luis Suarez bite incident, former boxing champion Mike Tyson -- who bit Evander Holyfield during a bout in 1997 -- became an involuntary part of the World Cup conversation.
On Saturday, he volunteered to be part of it, and poked fun at himself in the meantime. Check out his tweet after Argentina's win over Belgium.
Tyson, of course, was famously upset by Douglas in a championship bout in 1990. At the time, Tyson was the undefeated, undisputed heavyweight champion of the world.
