It took me halfway into the episode to realise that this was a retreat to the South Park movie. Seems weird that Terrance and Phillip are so old now, considering that the rest of the cast haven't aged at all. Hard to believe that they are setting up another large scale storyline while there's only 1 episode left, unless they are planning to continue on next season. Rest of the episode is pretty fun and I'm glad that this season so far has been a huge improvement over the previous.
