Doesn't matter. This is comedy. And it sounds funny. Nobody (except maybe you and five other people) are going to stop and think, "Hmmm, I thought the Saudis were Sunnis."
Besides, if you want to get snippy about it :-) , not all Saudis--citizens of that nation--are Sunnis--members of that faction of Islam. And not all Sunnis are Saudis. As far as I know, that is. But then, I might be full of shiite.
