"Yeah, this is the terrorist bomber."
I think that Seinfeld hit its peak in its early years, it was definitely past its prime at this point, but this is still a true classic, a diamond in the rough of the post-Larry David era.
Conrad the contractor was a great character, particularly his switch from needing Jerry there to not needing him, and the whole concept of taking a nap at work is genius. I love how Jerry Seinfeld and Gary Apple actually referenced this when Jerry did commentary for a Mets game.
If you are looking for an episode to convert someone into a Seinfeld fan, this is as good as any to show them.
