This episode is terrific and shows what may happen in 8 years though knowing Professor Frink's previous inventions, such as the sarcasm detector and the running house, it may not be too accurate. This episode had great future jokes such as shots that make Smithers straight and President Cletus.
Nelson being the father of Sherri and Terri's twins, finally understanding why his father ran off was great as was Homer's underwater house. Bender's appearance in the car was great (though it isn't the year 3000) as was Moe and his clone and spider clone. This episode can be summed up in four words: "No-one's gay for Moleman!"
