I watched an episode that I remember being one of my favorites. I found out that episode is called "The Tainting of the Screw" and I was surprised to find out that it was only the second episode of this great series.
When I was a kid I liked when I watched 'Kenan & Kel' becuase it never felt like a "Kids" show to me. After watching it as a 21 year old I still laugh and enjoy this show. My two favorite characters besides Kenan and Kel would have to be Kenan's grocery store boss Chris [Dan Frischman] and Kenan's father [Ken Foree]. Chris was a geeky boss that had some funny one liners and he was a bit of a push over. Kenan's dad was a BIG intense guy that did not like Kel very much. The interactions between Kel and Kenan's dad were funny becuase Kel would always get him upset unintentionally.
"Kenan & Kel" aired from 1996-2000 and has a rating of 7.9/10 on IMDb. A more recent show that was similar to "Kenan & Kel" that was also on Nickelodeon was "Drake & Josh" (2004-07), this series received a 7.5/10 on IMDb. A third attempt to a similar show, "Sam & Cat" was on Nickelodeon from 2013-14. They had Ariana Grande co-star in this series and the show still only received a 6/10 on IMDb. I don't think Nickelodeon will ever produce a sitcom as good as the original two best friends "Kenan & Kel".
The theme song for "Kenan & Kel" has to be the best song for any kids show...ENJOY:
