'Conan' Parodies Siri Commercial In IPhone 4S Spoof (VIDEO)

One of the most talked-about apps on the new iPhone 4S is Siri, the voice-activated personal "assistant" that can tell its users everything from the nearest restaurants to where babies come from.

But the trick is that they have to ask. And sometimes, it's just embarrassing to ask certain questions to a phone, whose response comes out in the voice of a surprisingly soothing lady. Conan O'Brien revealed last night that there are just some questions you shouldn't ask Siri, for your own sake. Like how far you are to Diarrhea Town.

Check out Conan's spoof of the new iPhone 4S ads touting Siri for some questions not to ask the personal voice assistant.
