Alright. I know this probably sounds weird, but eh, that's the whole point. Alright so what we're doing here is saying the silliest thing we can ever possibly use as soap. The next person must say if that would sell good or not. After they say that under it the same person would give another example. Ex. "Yes it'd sell good. Poo soap. Would that sell good?" Then so on. And please, nothing really above PG-13. I'll start!
Cheese soap. Would that sell good?
