@Victor Eremita,
Darkonius: One day there will be a science that shows how the light emitted by a burning substance emits a characteristic spectrum - and furthermore, that light reflected from an object moving away from the observer is shifted toward the red end of the spectrum, and moving towards one, the blue end.
Drunkentius: Hah, hah, he's gone most entertainingly mad! *hick* Let us entertain oursleves then. Tell us more Darkonius. What will this science show?
Darkonius: In three lines or less, I could not. Perhaps you might consider it?
