I can't find the article on their website, so I'll just go ahead and type it out:

Bucks fans show their game faces
Milwaukee -- A group of Milwaukee Bucks fans made their feelings about the state of the team known to owner Sen. Herb Kohl on Saturday night at the Bradley Center.
According to www.brewhoop.com, 39 paper bag-wearing fans paraded through the concourses before tipoff, halftime, and after the game.
But a small group didn't stop there. With about 5 minutes remaining in the Bucks' 99-77 loss to the Celtics, several fans with bags in hand got past ushers and made their way to the fifth row, where Kohl sits. Once there, the group put the bags back on their heads and gave Kohl a round of applause. An usher then escorted the group back to the concourse, but not before its point was made.
