Quote from Dr. Kelso in My Finale: Part 1
Ted: Aw, man He got my coffee wrong. Carla: How? Ted: It's dirt. Dr. Kelso: That may be because I told Donnie you thought his coffee tasted like dirt. Ted: Why would you do that? Dr. Kelso: Because Donnie is a vengeful, little punk, and I wanted to see what he would do. Ted: He's a convicted felony. He shivved a guy! Dr. Kelso: Aah, I love you Donnie. Muffin, please.
