Here are Shelby Miller and Jon Jay guest bartending on 'Watch What Happens Live'

You probably didn't know that "Unpack the Ball Sack" was a game that exists in real life, but we're pretty sure that you'll love Shelby Miller and Jon Jay on Bravo's What Happens Live anyway.

Get a load of these two @Cardinals fans! @jonjayU @ShelbyMiller19 pic.twitter.com/qRa9XtitUH

The show's host, Andy Cohen, is a St. Louis native who bleeds Cardinals red. So, for Tuesday's episode, he had Miller and Jay guest bartend (that's a thing that happens on the set) and play "Unpack the Ball Sack" with LuAnn de Lesseps and Billy Eichner (of "Billy on the Street" fame).

Watch the hilarity unfold, much to Cohen's delight, or give it a view just to check out the look on Shelby Miller's face.
