In the latest episode of CBS's "The Big Bang Theory" titled "Beta Test Initiation", Raj Koothrappali starts a relationship with a well-known woman - Siri.

After buying an iPhone 4S, Raj starts building a creepy relationship with Siri - taking her out for coffee, inviting her on double dates, and even dressing her, in "a nice black case".

If you are a fan of the show, you'll know that one of Raj's personality traits is that he has difficulty talking to women, so when Siri makes a human appearance, hilarity ensues.

You can check out the clip of humanised Siri below, but be sure to watch the full episode on CBS.
