“Mess Trick” is the process of simultaneous squatting with hyperventilation followed by sudden erect posturing to induce syncope. “Fainting Lark” is the “mess trick” combined with forced valsalva while erect. This rare behavior, when identified, has been isolated to autistic, cognitively impaired children. More unlikely is this behavior discovered in the cognitively-well population. A 13-year-old healthy girl presented with a first episode of seizure. The seizure was unprovoked according to the history provided by the patient and an eyewitness. Routine radiology and laboratory analysis could not reveal an etiologic source. After speaking with the adolescent in the absence of her parents, she admitted playing a “black-out” game performing the “mess trick” and “fainting lark.” The resultant myoclonic jerks were the result of intentionally provoked syncope. Therefore, high-risk behaviors should be included in the differential of first episode of unprovoked seizure in a healthy adolescent.
