When Bill Maher lays down his "New Rules", they're usually about some important or controversial aspect of our government or society -- and this time is no different. This week, Maher's taking on the divide between cat people and dog people. The bottom line? It's about poop.
Check out this exclusive "Real Time" preview below wherein Maher shares his thoughts on one of comedy's oldest tropes, and boils his preference for dog people down to the bathroom habits of both pets. It's pretty important stuff, people.
"Real Time" airs Fridays at 10:00 EST on HBO.
