For some reason, the Chicago Cubs did a Lucha Libre wrestling mask giveaway Tuesday night when they took on the Milwaukee Brewers. So, naturally, WWE Superstar (and noted Cubs fan) CM Punk was on hand to cheer on los Cachorros.
Oh, they also let him sing "Take Me Out to the Ballgame".
Unfortunately, the beer makers put the smack down (see what I did there?) on the Cubs and swept the doubleheader.
