MLS has continued to get better, and is tons of fun to watch. The LAFC-Galaxy game and the final were both especially great. At no point have I ever watched that league and felt like I was watching the soccer equivalents of Thomas Eshelman or Andy Tracy, even though many of those guys would look like exactly that in Europe (but not all of them - the pipeline of players leaving MLS, and yes, older players finishing here has also thrived).
It's the top American league, the team is in Philly, and at this point MLS is as popular as the NHL if not more so (in terms of both attendance and TV viewership). So yes, it is Philadelphia's fifth major league team, even if nobody turned over a car when the Union lost and the parade would have been small (I sure would have liked to find out how that was going to be handled had both teams won on the same weekend).
For sure the league's biggest challenge, whether in Philadelphia or California/Texas, is still winning over fans who follow other leagues. In South Philly I see kids wearing Union stuff but in the bars and restaurants they're going to be watching Liga MX. I don't know why anyone who watches EPL on TV all the time wouldn't also want to see some MLS games in person though.
And while I worship George Carlin, funny how a lot of stuff didn't age as well as you'd think (and that particular bit is from the beginning of the deadest part of his career). The football and baseball routine remains iconic because he's poking fun at them affectionately. That other monologue is him just taking random shots at all the other sports (besides basketball).
