Rugrats

Both of these stories are the first Rugrats episode to make its US TV debut not on Nickelodeon, but on the Spanish-language Telemundo network. The "12/20/1999" date for Telemundo is the earliest-known date, as Telemundo might have televised it prior to the Fall of 1999, when Telemundo's site opened. Nickelodeon US did not first show this episode until May 2001; when they finally did, this episode was already seen on all other versions of Nick worldwide and the local channels that carry the program, such as YTV, Canal Famille, France 3, Telemundo and, perhaps, AFRTS (yes, America's men and women in uniform overseas may have already seen this episode before the civilians).
