Why did the chicken cross the road?
For fowl purposes.
Well done!

Yeah! And besides, I like smaller paragraphs, and even separate sentences. Makes it much easier for my poor old eyes to follow. What I hate is people who clump their entire post into one huge block of text. Even with my reading glasses, it’s often just too difficult to track the lines of text without losing my place too much.
UN-altered REPRODUCTION and DISSEMINATION of this IMPORTANT Information is ENCOURAGED, ESPECIALLY to COMPUTER BULLETIN BOARDS.
Why did the dolphin cross the road?
For illicit porpoises.
That’s TERRIBLE!
