The owner of the brothel, concerned about profits showed up unexpectedly and told the madam that he needed a head count. The madam, taken aback, turned to Susie who was standing next to her and said “Susie, go get me a head count.” Susie left the lobby area and then returned after about ten minutes. “So,” asked the owner, “what’s the head count?”
“Three” replied Susie.  
“What?” said the owner, “That seems very low to me.” After an anxious pause, Susie stammered, “Well, you have to understand that all of the other girls are currently busy fucking their clients.”

LMFAO. You gotta count them too.
