When a joke falls in the woods

I made a joke this morning and it was like a tree falling in the woods with nobody around. I was talking to some people I work with on the other side of the globe. (it was kinda late for them) and I said at the end of the conference call: "Be careful out there."

Nobody got it but me. Or they got it because hill street blues is big in India and the just don't think I'm funny.

Either way, I was amused. That's really what's important right? That I am amused.
