Why not do a comic featuring the clowns? Humor could come from unexpected locations and situations. Would you want your clown accountant with you when you meet the government tax auditor? Would clowns on the Moon have a tiny lunar lander with countless clowns pouring out. One small step for Bozo, one giant pie in the face of mankind!
The clowns are so original as comic strip characters even Gary Larson didn't think of it!
