Robin: What the hell are you doing?
Marshall: Okay, Robin, I wasn't really mugged by a monkey, okay? I just made up that story so that Lily wouldn't buy a gun.
Lily: So, you weren't mugged by a monkey?
Marshall: No, what are you talking about, baby? Of course I was mugged by a monkey.
Robin: Great. Tell it to America. We're back in five.
Marshall: No. No. No. Not back in five. I wasn't mugged by a monkey.
Lily: Okay, that's it. I'm getting a gun.
Marshall: No, no. Don't get a gun. I was mugged by a monkey.
Zookeeper: Well, then, Bobo here is going away.
Marshall: Wasn't. I wasn't mugged by a monkey.
