The women of 'The Big Bang Theory' (Thu., 8PM ET on CBS) cracked the code of how to get Raj to talk to women without being drunk. They set him up with a deaf girl, played by Katie Leclerc ('Switched at Birth'). To facilitate communication, Howard joined them on their first date.
There, Raj was probably happy that Emily couldn't hear his attempts at flirting and boasting, as he couldn't have possibly sounded more ridiculous. Luckily, Howard toned it down a lot for him in translation. Unfortunately, Emily turned out to be a less than desirable girlfriend.
