On Fishbowls

"Why did the fishbowl cross the road?"

"Why?"

"To get to the bar on the other side."

A fishbowl walked into a bar and the bartender said, "Hey, didn't I see you in the joke above?"

"Yes, that was me," said the fishbowl.

"I thought you looked familiar. What will it be?" said the bartender.

And the fishbowl said, "Oh, the usual.  Some fish with some water, of course."

"How many fishbowls does it take to change a light bulb?"

"How many?"

"No one knows."
