It was pure joy to watch these episodes and recognize the jokes and motivations.
The result, in my eyes, was an hour (counting both episodes) of delicious laughter for those who have been watching South Park for quite a while. The creators, Matt Stone and Trey Parker, had decided to celebrate by doing a two-part nostalgic episodes that used old plots and gags from previous popular episodes they basically took elderly ingredients and baked them all together to make something new, yet familiar.
South Park recently had their 200 episode.
