Still struggling with a story,

I have got to a hard stage where finding a story fitting to what I want. I wanted something funny and simple. The characters also had to be dynamic and reusable to fit in with animation for television.
Much like the series of an animation on TV such as loony tunes with Bugs bunny and daffy duck. The character can be placed in to any environment and scenario and preform there story with out the Audience asking how or why they got in to this situation.

For help coming up with story I used the word salad to brainstorm an idea. here are them main pages I likes the look of most:

I decided on the Final Drawing Idea or two people fighting over the last bottle of milk in a super market.
I also had the Idea of it being two superheros fighting over the milk in there very day life's when they are not being super hero's. How ever the Re-usability of the characters made me wonder if this was the best of ideas.

I had the Idea of it being one Very fat and short character and the other tall and slender to make a good contrast in characters. I also wanted them both to be very angular and jagged  One based with squares and the other triangles.
