“Why did the rainbow cross the road?”
“Why?”
“Scientists do not know, but they believe it has something to do with social distancing.  And since this blog is Not All About Rainbows, watch out for that word believe.  Often, scientists do not know, but they believe.  In science, a lot of beliefs get passed off as facts.”

“What are rainbows’ favorite amounts?”
“I dunno.”
“Refractions.”

*

“How many rainbows does it take to change a light bulb?”
“How many?”
“Two.  One to change the light bulb, and the other to study refractions to find a way to keep light bulbs from burning out.”

A rainbow arced into a bar.  The bartender said, “Wow!  It is the first time anything has arced and not walked into my bar.  Congratulations!  Whatever you want is on the house.”
“Wonderful,” said the rainbow.  I’ll have some air.”
“Air?” asked the bartender.
And the rainbow said, “Isn’t there air on the house?”

*

“Knock.  Knock.”
“Who’s there?”
“A rainbow.”
“A rainbow who?”
“A rainbow who believes it can talk.”
“You can.”
“I thought so.”
“So, what do you want to talk about?”
“Refractions.”
“Refractions?”
“Refractions.  I am trying to discover, by using refractions, how to stop light bulbs from burning out.”

*

“Colors are the beliefs in the interrelatedness of all things.”
“Wow!  That sounds deep.”
“I know, but I have no idea what it means.”

*

And so the bartender brought the rainbow some air from its place on the house.  This air had no water droplets in it.  The rainbow drank it and disappeared.
