J.J. &amp; Jeff: J.J. & Jeff, known in Japan as Kato-chan Ken-chan (カトちゃんケンちゃん ) , is a side scrolling platform game for the TurboGrafx-16.  The Japanese version is loosely based on the then-popular comedy television show "Fun TV with Kato-chan and Ken-chan" which Vin Di Bona Productions used as its inspiration for the popular television show "America's Funniest Home Videos".  The game is best remembered for its off-beat characters and enemies, and toilet humor, including flatulence, urination and defecation in the Japanese release.  The game is often criticized for being too censored or sanitized when translated for America with most reviewers feeling that the Japanese version was superior in humor and gameplay.
