A little harsh don't you think? If your going to make these statements, why not explain to Dave in detail your dislikes so the next video could be less "embarrassing" as you say. I think they are trying to think of different ways to make a video go Viral, which is extremely difficult to do; especially when your adding something "not so interesting" in the mix. Let's be honest, who wants to watch someone clean? (unless of course the watcher is trying to find a fix for their stain/problem) No one finds cleaning funny, so I see what Dave and Scup are trying to do. They are trying to get more viewers on the product.
Viral marketing is not new. The objective is to get people to pass your marketing message on to friends, family and peers. Will Dave's video travel very far, you know, probably not. But, it will go further than no video at all.
Keep trying Dave/Scup. Your doing great.
