Shit, sorry. I'm still getting used to this site.
I don't have a favourite South Park episode because that's way too hard to answer. My favourite season sixteen episode thus far, however, would have to be 'Cartman Finds Love' followed closely by 'Butterballs'. The newer episodes are in my opinion still good, but sometimes they swing and miss. For example, I don't recall laughing out loud once during 'I Should Never Have Gone Ziplining'.
