Ok, I'm on my laptop, so this is a better version lol. I made a headless version of the Y U No Guy, and then I googled "Roadrunner PNG" and found a head to put on top. :-)
I used Snagit to make my headless Y U No guy, but I just used the meme generator to upload the image and then upload the head. I clicked the "Add Image" button after I uploaded the headless image and chose to add it "Inside" the current image. Then I just sized it to where it would fit.
