SLIM TO NONE

Les asked, "What's the difference between fat chance and slim chance?"

I said, "I think fat chance means there's no hope and slim chance means there's some hope."

I conducted a survey with the people I encountered today and nearly all agreed that fat chance and slim chance are the same thing.

Then my friend John told me, "You've got two choices: Fat and Slim and Slim just left town."

I think that "fat chance" is usually said sarcastically or ironically.
