What is this old cartoon?

Its one of those looney tune or warner bros. cartoons. I remember watching it when i was little but I can't remember what it was called and there are little details I remember. There was a detective and when he opened the closet 2 skeletons popped out(One was red and the other was white) also he told the maids and butlers to take out all the weapons that were in their pocket and when he turned lights back on there was a pile of guns and knives.
