At Wrigley Field in Chicago, a new tradition has been born. 

Catch a foul ball in your beer cup, then immediately chug the beer. 

It all started Saturday in the ninth inning when a foul ball landed right in a woman's beer! 

She held it up, then decided: why not guzzle the whole thing?

Perhaps inspired by the viral video from the day before, this guy followed in her footsteps Sunday, dropping a foul ball into his beer before downing the whole thing.
