Well, first you save the blank version of the meme:
[link]Usually people drag it into any art program (GIMP, Photoshop, SAI, MSPaint even) and draw directly on it with a tablet or a mouse. If you can't afford SAI or PS, GIMP is a free art program you can download, and MSPaint is on every Windows PC.
You can also draw the answers to each question on paper and scan them in, if you have a scanner, or upload photos of them off a camera, and paste them into the boxes. Whatever works for you!
Hope that helps
