By the end of Seinfeld season 7, David feared that the Seinfeld writers would run out of interesting things to write about, and became stressed by the pressure to produce better material for each subsequent episode after seven years. Playing on the criticisms of the Seinfeld finale, a season 7 episode of Curb Your Enthusiasm featured a Seinfeld reunion (fictional as it was), with David writing while Jerry, Julia Louis-Dreyfus, Jason Alexander, and Michael Richards reprised their roles. For one, Curb's average number of episodes per season was far lower than Seinfeld's, with David only having to worry about ten episodes per season over two decades rather than double that for Seinfeld over eight consecutive years.
