April Fools' Day

 April Fools' Day (AFD) walked into a bar and the bartender said, "What will it be?"

And AFD said, "I'll have a joke on the rocks, please."

The bartender left.

A few minutes later the bartender returned with the government on granite.

"Why did AFD cross the road?"

'I dunno."

"Time marches on."

"Knock.  Knock"

"Who's there?"

"April."

"April who?"

"April Fools!"

"How can it be April Fools when you are still at my door?  You should have knocked and then run away."

"How many April Fools' Days does it take to change a light bulb?"

"How many?"

"Only one, but the light bulb has to burn out on April First before noon."

"What does AFD have in common with cumulus clouds?"

"What?"

"AFD and cumulus clouds have nothing in common."

And the alien said, "Okay, we abducted April Fools' Day.  So, where do we shove the anal probe?"

"What do AFD and cumulus clouds have in common when they are inside a surrealist art gallery?"

"Nothing?"

"Nope.  Boxing gloves."

"Knock.  Knock."

"Who's there? . . . Who is there? . . . Who's there?"
