Here's what we did till now, I hope it's comprehensible:
Samurai Jack - First letter starts with S, so the next ones needs to end with S.
(The) King of Queens - First letter for this is K, next one needs to end with K.
South Park - It ends in the K (used in King), and starts with S, so next one ends with S.
Bones - Uses the S from South as last letter, Bones starts with B, so the next one ends with B.
Smash Lab - Ends with the B from Bones, word starts with S, so the next ends with that.
(The) Simpsons - Ends with the S from Smash. But starts with S, so the next words ends with S.
