EXTREME LIKE DINOSAURS EXPLODING!!! (Sketch)

I think this was said by Ryohei Sasagawa, but whenever I look for it, I only find an inappropriate fanfics and a funny piece of flair on facebook. Even though I don't like where the saying came from, I still think it is hilarious and I bet Ryohei would say it. This is just a random sketch; If you can't read what the people are saying in the background here it is from right to left: Person one, "I told him not to drink that milk."; person two, "Should we call a doctor?" Person three, "didn't he make that in the 5 grade?"
