Define 'Irony'

I bought a 'Poker Tip of the Day' calendar last weekend to keep on my desk here at home. (Of course, a Dilbert one sits at my desk at work.) Anyway, the tip for this weekend defines 'Narrowing the field' as:

"Betting or raising in the hope that you will drive some players out of the pot whose hands are currently weak (worse than yours), but who might improve their hands if allowed to stay in."

So, all weekend, I've sat on the Play Money 5/10 No Limit Hold-Em tables seeing the definition of narrowing the field on tables where it is impossible to do so.
