My humor is often obscure enough that only one person in the room gets the joke, but that person thinks it’s uproariously funny.
Here, try this one out and see if you’re that person:
I went into MacDonald’s and ordered a MacGuffin. They gave me a box with a gilded rhinoceros horn that an unscrupulous arms dealer wanted very badly.
Well, I know what a MacGuffin is, but I don’t know about the rhino reference.
The congressman outrunning his constituent when chased by a bear metaphor was pretty funny.
The rhino horn, you see, would be a MacGuffin. If you ordered one.
You see my genius yet? It’s around here somewhere.
