Just a silly little sketch of strip...I realized I hadn't done that many of Mr J and Harley. Also just practicing layouts and timing for comics.
I do a LOT of humorous fan art, and although this is funny, it also shows these two being 'softer' without being too lovey dovey. The fun is still there.
I think the Joker would not find anyone worth keeping around unless they play their own jokes on him now and then, and knowing Harley as well as we all do, she's always trying to seduce Mr J or trying to mummy coddle him which I find adorable.
I was thinking playing on his vein side, telling him there's something on his face or cheek would give her an excuse to kiss him. I made it his teeth because I love drawing teethy grins, even though there isn't one here. I was going to have the Joker say 'Did ya get it?' in the last panel, but I like what I put in the end waaay better. It's a play on words, they both have a joke in here, and neither are being selfish or self centered. He still ends up patting her on the head like she's just a 'sweet kid' in his eyes, but there is a hint of so called adoration there.
