Spotted a penny whilst riding -- uphill, into the wind. Thought, no, I'm not losing my momentum for a lousy penny. So the question enters my head, "What denomination of coin will get you to stop?"
I figured maybe, MAYBE a nickel. Sure enough, within 20 yards a quarter appears and I'm all over it.
Attributed to Winston Churchill:
Churchill: Madam, would you sleep with me for five million pounds?
Socialite: My goodness, Mr. Churchill... Well, I suppose... we would have to discuss terms, of course...
Churchill: Would you sleep with me for five pounds?
Socialite: Mr. Churchill, what kind of woman do you think I am?!
Churchill: Madam, we've already established that. Now we are haggling about the price.
