I got bored this evening:
There once was a man named Saul Kripke
Who said I will force you to pick me
I designate rigidly
Yet you look at me frigidly
So come on, dear girl, and just lick me.
Oh come now, my dear Mr. Kripke
I know not what you mean by 'just lick me.'
For the word 'me,' you see
Is indexed to thee
And your theory of reference can't trick me
"Ah ha!" then said old Mr. Saul
I can tell that you're trying to stall
But with a theory so long
How can I be wrong?
By my side those descriptivists pall
I don't care about size, Mr. Kripke
And I know you're still trying to trick me
Proper names still refer
As descriptions I'm sure
And your rigid old theory shan't stick me
It's likely that no one will find this funny without some background in the philosophy of language (and even then it's still pretty likely, probably). For reference: rigid designation, Saul Kripke, descriptivism, indexicals.
