These tourists got more than they bargained for as they examined the architecture of a Chicago bridge:

Tourists aboard an architectural sightseeing boat on the Chicago River -- a premier city attraction -- were doused with raw sewage Sunday afternoon as the vessel hovered under the Kinzie Street bridge, the tour operator and Chicago Police said.

More than 100 people were aboard the packed Chicago's First Lady at 1:20 p.m. when the sewage dropped from two tour buses passing overhead, said Lynn Osmond, president and CEO of the Chicago Architecture Foundation.

The real loser in this story is the company who refunded $26 to all passengers. And the river.
