After William Fairchild's comment on the previous version of this video, we've replaced United Kingdom in the S10E21 caption with Scotland and in the S15E04 caption with England (in spite of Tony Blair welcoming the Simpsons to "the United Kingdom").

Antarctica isn't a country, but good enough for this compilation. Although the Simpsons go to Calgary in S14E12 (I'm Spelling as Fast as I Can) for the Spellympics, Canada isn't really featured, so that episode didn't make the cut. Some episodes repeat the couch gags, or skip the couch completely. Danny Elfman's theme music during some of the gags generated copyright claims on this latest upload, so his music has now been dropped from those clips. "White Rabbit" in the pharmacy in S16E06 has been replaced with "Happy Mistake" by RKVC.
