I'm thinking that as well as all these poo bags in the air (some filled with dog vomit) - heck, why stop at just dog stuff! Cat poo, human poo, diarrhea etc... Then, tell people there are also some bags with $100 notes in them (Wrapped around a weight so they don't fly away). Shoot them down! Hey, you may be lucky... then again ...
I'm thinking umbrella sales would skyrocket
