"Shaggy Busted" was the third episode of the Harvey Birdman: Attorney at Law.
Full Summary Edit
The Mystery Machine, playing music reminiscent of the early Doobie Brothers, is pulled over for erratic driving. The driver, Shaggy Rogers, claims that they heard there was a monster around the old abandoned cotton mill and he was going to meet up with the rest of the gang, to try and catch it. The officer thinks it quite obvious he and Scooby are under the influence, but when he asks them to step out, they speed off.
Back at Sebben & Sebben, Harvey is having trouble keeping track of his files, and starts interviewing for a clerk. He is impressed by a young man named Peanut who dresses much like himself. Despite his annoyingly laid-back persona, he decides to hire him.
Fred Jones comes in to hire Harvey, who mistakes him for a gang member, his ascot being his colors. Fred brings Harvey to the jail to see Scooby and Shaggy, but they still act as though they're high. The rest of the gang tries to assure him that they're not high, just stupid.
The case goes to court, and Spyro acts out the traffic stop theater style as Peanut hits on Daphne; he is so cool as to be practically unintelligible. The arresting officer claims to have found drug paraphernalia, but Harvey manages to show this as circumstantial. Velma goes on the stand, and tells Harvey that they're just always hungry and they laugh when nervous. This supports an earlier defense claim that clips of old Scooby-Doo cartoons shown by the prosecution have been taken out of context to show Shaggy and Scooby as total stoners. On the second day of the trial, Fred and Velma burst into the court with the monster in custody. They unmask him to be Old Man Bakov, and he tells of his nefarious plans. Everybody laughs heartily, including Bakov.
