In the 1991 movie The Naked Gun 2 1/2: The Smell of Fear, there is a joke I don't get. It's in the scene after Frank Drebin finds out Jane Spencer is going out with one Quentin Hapsburg. He gets depressed and heads to the "Blue Note" jazz bar. There are four pictures on the wall:
The first is a street with the city behind on fire (I presume this is the San Francisco earthquake)
The second is the Hindenburg
The third is the Titanic
The fourth is some guy who looks like DA Jack McCoy from Law & Order.
Who is the fourth guy?
