Here is some trivia:
The syndication version of the episode "I Was a Teenage Taylor" [6.7] contains a scene previously unincluded in the primetime version in which Tim brings his Halloween guy to the Tool Time set.
Various episodes have shortened or slightly-revised opening sequences, usually with the theme appropriately cut or significantly revised.
Syndication prints replace the first season opening credits (in which the cast's names are printed in a different font), with the opening credits that were used beginning with season two. Although the opening sequences are the same across the two seasons, the theme tunes are not.
