NYC FailBomb "a Rube Goldberg contraption"

"I call this a Rube Goldberg contraption. It's the 'swing-the-arm-with-the-shoe-that-hits-the-ball-and-knocks-over-a-stick-that-knocks-something-off-a-shelf, and it is all supposed to work."—James M. Cavanaugh, quoted in the NYT, on the NYC FailBomb. Cavanaugh is a former bomb expert with the ATF who "investigated car bombs and tracked the Unabomber, Theodore J. Kaczynski, and Eric R. Rudolph, the bomber of abortion clinics and other sites."
