Awww, look at how cute Harley Quinn is on the 100% cotton Harley Quinn Mallet T-Shirt! She's so adorable with her cute 'wittle' mallet and pop gun. OH NO WHAT IS SHE DOING? She's hurting me! HELP! Okay, I got away from her...I distracted her with a lemon meringue pie. I don't have much time so you'll just have to appreciate the Harley Quinn Mallet T-Shirt as quickly as you can. Emulating a carnival like style, the Harley Quinn Mallet T-Shirt may cause the Joker to get jealous.
