Susan Sarandon Spanks Pig At Of Montreal Concert (VIDEO)

Georgia indie band Of Montreal always gives an elaborately loopy show, but Tuesday night at NYC's Highline Ballroom their audience was in for an extra surprise--Susan Sarandon dressed as a schoolmarm.

Sarandon took the stage during "St. Exquisite's Confessions," grabbed a grown man dressed as a pig by the arm, bent him over her knee and wailed away with a ruler. The spanking begins around :35.
