Police in Chicago had to close off a street near Grant Park because of a suspicious, but delicious, vehicle in the middle of the road.
Officers grew concerned when they spotted a strange contraption in the street. It was a can of Chef Boyardee beef ravioli attached to a set of wheels and connected to a thin green wire.
Investigators blocked off the street and shut down the city's "L" train station in the area. It was eventually determined that the can-on-wheels was a science project belonging to a student from nearby DePaul University. It's unclear how or why it got into the street. (WBBM-TV)
