I was getting some online just now.
Then these popped up on the main page of FTD.
The way my mind works, I immediately thought of getting some just so I could go out in public and randomly chuck one as hard as I possibly can at somebody. At first they'd be all, "what the fuck?! You just hit me with a rock." but then they would see the incredibly heartfelt and romantic message and be all, "d'aww I can't stay mad at you."
This concludes your foray into the way my mind works sometimes. Curtain closed.
