Can I get to feel stoned the whole time?
Make my “schlong” twice as long! Then my statue will outdo the statue of “David”.
“If you are looking for more subjects may I suggest …”
Dr. Carson, is that you?
Please Don’t turn me into a Quartz statue. I can’t stand Quartz! 
Let me get in my car for one last drive, why don’t you come along, Medusa, sit in the passenger seat…
Option 1; my passenger side air bag has been disabled, get up to top speed, find a handy bridge abutment and slam the passenger side of the car into the abutment, crushing Medusa, while I have a little better survival chance as my airbags work
Option 2; instead of a bridge abutment, get the car T-boned on the passenger side
Option 3; flip down the passenger side sun visor, which coincidentally has a vanity mirror in it… Now, I didn’t technically use a mirror directly on her, one just happened to be there
Option 4; get a Weeping Angel to touch her… 
“Medusa, hon, can we talk? Girl to girl? Can you steer away from those white marbles? I don’t want to spend eternity with my ass looking gigantic. You get that, right?”
On the base of my plinth, please chisel the words, “Inventor of Pornography.”
Even though I die, my fame will last forever.
Would using a mirror on her actually work? I was under the impression that Perseus was able to behead her by looking at her reflection on his shield while attacking her so he could keep track of her movements without being turned to stone, as he would have been from staring at her directly. Or is that what you meant?
A box of angry mongooses, please.

Sure; she’ll have to remove your testicles to compensate, though. Before your petrification.
Mongopods.
“Wait — Can I write your biography first?”
Blindness
No request. I just reiterate that, like that bitch Arachne, she totally had it coming.
Can I have a mirror?
For that impertinence she has you pose with a clay tablet and stylus. And still petrifies you.
That’s what she does anyway. But for your impertinence you get bitten.
Nope. Any extra definition will be done by her.
Medusa is amused and has you pose with a parasol and a bowl. You still get petrified.
Granted! Unfortunately you’ll be dead and won’t feel anything at all.
Nope, you’re dead. Sorry about that. But future owners may get tactile pleasure from feeling your statue.
Bad BubbaDog! 
This comes close to my own thought: have my name inscribed on the plinth.
Nope. She’s not going to risk the wrath of Priapus.
Perseus comes onto the island of Medusa. He has a magic spell to un-petrify statues, but it only works for an hour.
He picks out two statues, one male and one female, and un-petrifies them.
“OK, go off and do whatever you want for an hour”, he tells them, and they run off into the bushes. Perseus hears much giggling. He peeks into the bushes.
The male statue has a pigeon. He says to the female statue “OK, now *I *will hold him down while *you *shit on him.”
