well...many years ago there used to be a TV quiz show called "The Who, What or Where Game"....contestants would choose a topic, then could ask for easy or more difficult questions about it, with correspondingly greater rewards. (double money, triple money..etc..)

One day I had come home for lunch and was watching the show with my ex-wife and one kid. The topic was 'great historical battles', and I said "I'll take the 2 for one (double money) question...and the answer is "Thermopylae"...they looked at me strangely.

Sure enough, the contestant choose 2 for 1, and the question was "at what battle did a small Greek force hold off a much superior Persian army...etc.."

The wife & kid looked at me and asked "How'd you do that?"

Then I got to explain about inductive reasoning and smirk for awhile.
