Scooby Doo, my favorite cartoon character growing up, celebrates his 42nd anniversary this week.  There have been many incarnations since its debut, including a recent brand new series featuring the gang called Scooby-Doo: Mystery Inc.  The new show isn't bad, although there is now sexual tension within the group which is a bit odd.

However, nothing beats old school Scooby so let's celebrate the legendary canine and his pals this week and enjoy clips from a vintage episode after the jump.

Scooby-Doo, Where Are You! premiered on September 13, 1969. This cartoon introduced four kids and a dog named Scooby-Doo. These kids were Daphne Blake, Freddy Jones, Velma Dinkley, Norville "Shaggy" Rogers, and their mascot. They traveled around in a green van known as "The Mystery Machine"… More and solved many scary mysteries along the way.

In 1972, this show became The New Scooby-Doo Movies, which were hour-long episodes in which the gang teamed up with famous animated stars and celebrites to solve mysteries. This format aired until 1973.

Scooby-Doo was so popular to Hanna-Barbara that it spawned many different cartoon series throughout the 1970's and the early 1980's. These shows were as follows: The Scooby-Doo Show, a revamped format of this show, Scooby and Scrappy-Doo, which introduced the character Scrappy-Doo, The 13 Ghosts of Scooby-Doo, and the last incarnation, A Pup Named Scooby-Doo, which featured the cast as kids. After more than a decade-long absence of original weekly shows, a new series, What's New Scooby-Doo?, began airing in September 2002.
