It doesn't happen very often. But every now and then, an animal will run onto the field during a major sporting event and wreak havoc. From pigeons to squirrels, we've pretty much seen it all at this point. And we're sure we will see more in the future. To provide you with some great examples of it happening, Bleacher Report just assembled a list of 20 animals that looked like they really wanted to play sports over here. Too bad they got chased away before they could actually do it.
