10. Mr & Mrs Koothrappali (Brian George & Alice Amter)

"So... hot in India?" "Of course it is, it always is, it's India." Raj's parents occasionally appear on a computer screen during Skype conversations with Raj and his sister Priya. Without fail, the calls always come during inopportune moments and Mr & Mrs Koothrappali always have two cents to put into the mix and their opinion is usually casually offensive. Whether it's insinuating Raj or Leonard & Sheldon are gay (in the pilot episode) or that Penny and all American women are un-dateable... they certainly can't keep their feelings to themselves.
