Burnett shakes up Chicago’s St. Patty’s Day

Shamrock

Leo Burnett celebrated St. Patrick's Day yesterday by dumping a giant McDonald's Shamrock Shake into the Chicago River, which the city turns green every March 17 as part of the Irish celebration. Some think it looks like littering, but minty ice cream is surely among the least objectionable substances to have been emitted onto the streets of America yesterday. Plus, unlike in Tennessee, no leprechauns were harmed.
