Yes, that's Bill Murray taking tickets at an independent league game
Celebrities - they're just like us. Sometimes they just throw on the old bucket hat/camo shorts/Hawaiian shirt combo and snag a summer gig taking tickets at the local ball field:
Bill Murray, actor/American hero, is a part-owner and "team psychologist" of the St. Paul Saints of the American Association of Independent Professional Baseball, and on Thursday he was on hand to help the team celebrate their last game in Midway Stadium before moving to a new home in 2015. Maybe taking tickets doesn't seem particularly celebratory to you, but who are we to claim to understand the unfathomable, god-like workings of Bill Murray's mind?
