When Yang refuses to brush his teeth and see a dentist, he catches Wild Hare Tooth, a rare and dangerous disease that causes him to act like Bugs Bunny. Meanwhile, Edna is craving some rabbit stew, and sends Carl out to fetch her some fresh rabbit. Will Yin and Yo be able to find Yang before Carl does or will Edna be able to make rabbit stew?
- This episode features Carl as the main antagonist.
- The title is a spoof of the documentary An Inconvenient Truth.
- This entire episode is a direct parody of Looney Toons, with numerous references throughout:
- The short intro scene mid-way of the episode is a direct reference to the intro used in the Looney Tunes shorts.
- Yang's cartoon-like depiction (as per mentioned above) is a reference and a parody of Warner Bros. Bugs Bunny. His mannerism references those of Bugs and Daffy Duck to the point of being nearly identical, such as one of Yang's lines: "Eh, what's up, dork?", and the Daffy Duck-like laughter.
- Carl's hunting attire is identical to Elmer Fudd's and his weapon of choice is a laser bearing the appearance of an old-model shotgun used by Fudd. Carl also makes a reference to this earlier in the episode, noting the less strict reinforcement of animation censorship during the time of classic cartoons (1920s onwards) and calling it "a time when firearms weren't very dangerous".
- This episode has an alternate, Looney Tunes-style title card.
- When the fox (a reference to Looney Tunes Wile E. Coyote) contacts a company for hazardous equipment to capture flamingo (a parody of the road runner) (again referencing the same coyote), the company is depicted as Apex. This is a direct reference to both Acme and Ajax, fictional companies depicted in Looney Tunes and Mickey & Co. cartoons respectively.
- There even a flamingo (a reference to Looney Tunes Road Runner) he said "honk honk" instead of "beep beep" he also could move very fast (again referencing the same road runner)
- When you pause the part where Yang runs away, The Tooth Fairy appears to pick up his teeth.
- At the last seconds of the episode, Yin and Yang break the fourth wall, addressing the audience about the issue of dental care. Breaking the fourth wall has been a recurring element as of Yin Yang Yo!'s second season, seen in episodes such as This Yang Isn't Brought To You By..., Situation Tragedy and A Walk in the Woods, just to name a few.
