This Cubs fan shows us all what summertime baseball is all about as she catches a homerun in her beer cup, and finishes off what was left.

Actually, when you think about it, this is really amazing.

I've been to hundreds of games and never caught a ball.  So for her to catch one, and do it with a beer is really incredible.

Check out the Vine of her celebrating with what's left of her $12 beer.

As good as her catch was, it still ranks as the second best catch by a fan at a Cubs game.  I mean, this old guy nearly died to pull in this ball!
