ColumBUS
A ship
The riddle about "which bus can cross the ocean" typically refers to the play on words involving a "submarine." The word "sub" is a common abbreviation for "submarine," which is designed for underwater travel. The humor lies in the unexpected twist that a bus, typically thought of for land travel, can "cross the ocean" when interpreted as a submarine.
