this is in season 1, episode 11 (Bad Replicant) the scene where Meatwad and Frylock first meet Master Shakes replicant. When Frylock says "lets all go get blood" look at the picture in the background above the bookshelf. It's a picture of Frylock and Dr. Weird. An interesting thing to note is that The Aqua Teen Hunger Force and Dr. Weird have never met in person in any episode prior to this one.
