Claim: Arena Naucalpan 36th Anniversary Show is IWRG's longest-running show, and the main event was a Triangular de la Muerte match.
Evidence: The show is IWRG's longest-running show, predating IWRG being founded in 1996 and is the fourth oldest, still held, annual show in professional wrestling. The main event was a Triangular de la Muerte ("Triangle of death") match, with three teams competing against each other in a match where the losing team would be forced to unmask or have their hair shaved off under Lucha de Apuestas, or "bet match" ("betting fight"), rules.
