Here's something I came up with. It revolves around the letter "J":
Stimpy J. Cat was voiced by Billy West,
Who also voiced Philip J. Fry in Futurama, created by
Matt Greoning, who's most famous character is Homer J. Simpson,
Who found out that his middle name actually is "Jay", which is not far off from
"Jake", as in Jake the dog, who was created by Pendleton Ward, who also made
Bravest Warriors, an internet-only cartoon series, and
The first internet-only cartoon series was "The George Liquor Program", made by
John K, who also made Stimpy J. Cat....
