Don't Fear the Roofer is a terrific Simpsons episode with a really well written storyline and loads of very funny scenes. It's a very different episode, as we see the family expect Homer may be going insane because of his constant talking of a roofer that no one else has met. There is suspense here as we ourselves wonder if this roofer is real or if Homer really has lost his marbles, and you will be anxious to find out the truth. I think the writers should have taken advantage of Dan Castellaneta and Ray Ramono's talent for improvisation, the scene at the end where they talk about Everybody Loves Raymond was hilarious and clearly ad libbed, I would love to have seen more parts like this. Ray Ramona's guest role as, you guessed it, Ray, is outstanding, without a doubt one of my favourite once off characters in the show's history, his friendship with Homer was fantastic, they also brought Stephen Hawking in to it nicely. A very well written and exciting twenty minutes, Don't Fear the Roofer is a highlight of the sixteenth season for sure.
Homer makes friends with a roofer who he hires to fix the house, however, the rest of the family suspect he may be crazy as no one else has met him.
