"If you are happy and you know it quack quack if you are happy and you know it..." This is what I heard for about 2 hours on a Ride the Ducks land/sea ride. 

Every time I  move to a new city I take an official tour of the city (usually by bus). It is usually pretty cheesy and meant for tourists with children, but it helps me to orient myself in the city  and it provides some historical information I would otherwise not have looked up myself. I had always wanted to go on a duck boat mainly because I wanted to see a car drive into the water successfully.  Even after the trip was over I think that was the highlight.
