When you've gotten a good look at the first picture, press space. From then on, it will just show you each pic for four secs and then switch to the next one automatically.
I got all of these off pintrest, from a character named "Grumpy cat." Of course, all these jokes are a lot funnier if you go find Grumpy cat on the web or on pintrest, because the thing that makes them really funny is the pictures. (which i dont know how to get onto scratch.) so i just made my own, which aren't as funny as the originals. Yeah, and instead of a cat, its now a person, which is why I called it Grumpy kid!
