 The DVD release of "The Complete First Season" has a slighty shorter version  of the episode "The Telltale Head" than was originally telecast. Near the end  of the network version of the episode when the mob is about to attack Bart  and Homer, Bart makes a speech to the mob about "taking the towns heritage  for granted", which finally convinces the mob to let them go. On the DVD  release, however, this short speech is absent and it quickly jumps to the mob  deciding to leave them alone &emdash because it did not exist in the original  reel of the episode that Groening and Brooks delivered to the Fox Network!  The speech Bart made about the mob "taking the towns heritage for granted"  was the editorial creation of the network censors in compliance of the FCCs  1989 ruling that every serial animated television show transmitted include at  least 28 seconds of educational content.
