"I recorded an episode of The Simpsons, and that was such an incredible life dream for me that I had kind of lost sight of. For a couple of decades, I've been ape-s**t about that show, and I thought, 'It would be so amazing to be on that show, but that could never possibly happen,' and today it happened, and I was incredibly on cloud nine." Actor Nick Offerman has fulfilled a life-long dream of filming a guest-spot on U.S. animated series The Simpsons.
