Recently I discovered that if I drive on a certain section of the I-35 upper deck when there's not much traffic I can hit the expansion joints in time to the music on the radio. You have to be going just the right speed and goose it a little when necessary, but when it works it's like an automotive version of Rock Band and is totally fun.
I suggest trying this to a song with a moderate tempo. Anything too frenetic or slow could get you a ticket or a middle finger.
