Ed Koch to a reporter
Ed Koch, a noted American lawyer, politician and political commentator, was mayor of New York City from 1978 to 1989 and was well known for his quips and one-liners.
After the reporter kept pressing Koch about a statement he had made, the politician lost his temper for a second:
"I can explain this to you; I can't comprehend it for you."
Well you see, they were looking for witty retorts.
