This is from Jonathan Larson’s Rent. The song is “Goodbye Love”:
I can’t figure it out. As soon as you add a third direction, it’s no longer a street, right? It’s some kind of parking arrangement, or a separate street. Love is not a three-way street, but only because nothing is a three-way street. Roger should have sung:
Roger: All your words are nice, Mimi,
but everything’s not what nothing is.
