Joker: Event: T-shirts
As the Joker stepped out of his flat, he tripped over something. A box. He looked around, half expecting to see a squirrel or something. He poked the box with a toe. It did not attack him back. Yes, he expected it to, with good reason.
"Hmmm, well, curiosity killed the cat...good thing I'm not feline!" He grabbed the box and went back inside, tearing it open.
When he saw the t-shirt inside, he clapped his hands. "Perfect! It even matches the STEAMROLLER!"
He quickly changed shirts, and then continued on his way out the door.
