Yourselves?

In the 0:56 of the following cartoon, the man says "Actually, girls, to him, well, you're pretty gross yourselves..." I assume that this yourselves has the work of emphasizing you. Is this correct? And I thought this sort of yourself/ves must be put just behind you(for example, "I've been wondering if you yourselves have any idea why she came") but that was put behind the adjective. Is this order OK?
