A City of Ater found this poster -- artist unknown -- in Exposition Park yesterday. Don't get it? Well, as the Morning News reported, Michael William Liebermann, co-owner of the Pizza Lounge in Exposition Park, was charged with misdemeanor assault last week, accused of beating a 61-year-old man with a pipe after the man tried to use someone else's credit card to pay his restaurant bill. Funny? Too subtle? Too mean?
