In this episode, Tim and Al go undercover to A1 Salvage. While they are there, they meet George, who Al says they met in prison when they were scalping tickets. George says that they showered together, and near the end of the scene, he says, "I can't believe I let you borrow my soap."
"No, No, Godot" is the episode where they were scalping tickets. Just before Tim and Al get out of prison, Tim states that they were only there for 45 minutes. Also, they never changed clothes. So Al couldn't have showered with George.
