Q: What's light green and a subspace of the complex plane? A: Real lime
The canonical variant here is "What is green, far away, and compactifies the real plane? A: The lime at infinity."
One friend of mine at university came up with: "What is green and determined up to isomorphism by its first Chern class? A lime bundle." I prefer yours, not least because I actually know what it means :-). The Banana-Tarski one isn't close enough to homophony for me. -- g
