The first appearance of Timmy.
This is the first time Kenny is seen outside his usual outfit in the series, after having seen both his face and hair in the movie. It's shown that he has yellow hair, but even then his face is not seen.
When the television reporter mentions the address of the child with leukemia he says "off Arapahoe Road on Emporia Street, a half mile east of I-25." This is a reference to a long running commercial done by a local Colorado jeweler called the Shane Company. When the reporter is done speaking he says "back to you Tom." Tom Shane is the owner of the Shane Company as well as the man who says the lines in the commercials.
At the time of this episode's airing, a Sega Dreamcast sold for roughly $199, making it one of the cheapest consoles on the market.
