Thank you-- #1 What constitutes a 'clown' from-let's say a 'mustard and ketchup'? #2 What separates a bionic clown from a regular clown? #3 Are clowns particular to a certain maker/company(Peltier or other as well)? #4 Do clowns have size limitations, or can they come in all-ish sizes? Thanks for letting me increase basic information.
