Apparently Jon and Kate are having marital troubles. Not surprising given their household. So I was thinking the show might need another angle as they transition to a new stage in their lives.
I think you can kill two birds with one stone here. You could transition from the current show to a new version that could hit the much sought-after 18-35 male demographic as well.
Here is my idea:
Jon and Kate Plus Ape.
The premise is that you would lock the two recent divorcees in a house with a giant carnivorous ape. Cameras would roll as hilarity ensued. The kids could come over once in a while to capture the original show demographics.
