Crows on a Fence

I recently read this snippet and it stayed with me. I am sorry, but I just can't remember where it came from. If you recognize it please let me know.

Here's the question.

There are five crows sitting on a fence. Two decide to fly off. How many are left sitting on the fence?

Think about it

Don't look at the answer yet.


Think some more.
























Okay here's the deal. There are five crows still sitting on the fence. There is a big difference between deciding to do something and actually doing it.
