After a long absence, Tread Perilously returns to the world of Tequila and Bonetti with an episode called "Fetch This, Pal."
When Tequila and Bonetti are called to the scene of a possible bomb scare, they are accosted by the head of the LAPD's K9 unit (guest star James Tolkan) who refuses to give them access to the building. Soon, Bonetti signs Tequila up for a certification test the dog has no intent on passing, even as the stakes get higher. But will any of that matter when bomb scares become real bombings and the prime suspect appears to have history with the K9 unit?
Erik declares the episode to be both inefficient and irritating. The tonal whiplash also works against it with scenes becoming too dramatic and too comical at the same time. Justin is confronted with another television series he can't tell is real. He also imagines other actors as Tequila even as the character earns a new voice. Don Fanucci makes a surprising appearance. George Lucas turns out to be a fan of an obscure Ewan McGregor film. A theory emerges regarding how Tequila's riffs are generated. James Tolkan is praised even as Tequila attempts to make fun of his bald head. The pair try to figure out how the dog became a cop and the piano montage gets another look.
