WOW monkeyfaceperson! There really is no need for your comment. If you don't like the idea, just move on and don't make it.
Actually monkeyfaceperson kids would love this. Anyone who appreciates the combo of chocolate and peanut butter would also find this appealing. You are the one making the cupcake so you can choose the amount of icing, think about it! If excess isn't your thing go light. Use a little common sense...
