Born on April 30, 1981, Kunal has an Indian ancestry. Before receiving worldwide popularity with "The Big Bang Theory," Kunal acted in several other movies and TV series. As the actor celebrates his 35th birthday, here are some of his best quotes from "The Big Bang Theory:"

Raj: Okay, here we go.
(To Leonard & Penny) Say cheese.
(To Sheldon & Amy) Say cheese.
(To Howard & Bernadette) Say cousin.

Howard: Hey, I threw out the first pitch at an Angels game.
Josh: Wow.
Bernadette: He did it with a robot.
Josh: You had sex with a robot?
Howard: That's not what she meant.
Raj: But technically, yes.

Raj: I'm sorry I'm so late. I was on the phone with my mother.
Bernadette: How is she?
Raj: Pretty good. She bought the book "Eat, Pray, Love", and used it to set my father's Mercedes on fire.

Raj: I've said this before and I'll say it again: Aquaman sucks!

Howard: So in addition to being crazy, you're resting the weight of the mission on your athletic prowess?
Raj: Yes.
Howard: The man who crashed his stationary bike?
Raj: I didn't crash it, okay? My play-list was too up tempo, I got light headed and I fell off.

Howard: You know, when I was a kid I loved going there but I could never get a ride.
Raj: Ooh, what if we got a van and drove around, and picked kids up?
Sheldon: Nice! Like at parks and schools.
Howard: Toy stores, puppet shows.
Leonard: Hold on, so your idea is to get a van and cruise the streets looking for kids to pick up?
Sheldon: Yes!
Leonard: And are you going to use candy to lure them in?
Raj: We are now!

Raj: Oh man, first monster I see I'm gonna sneak up behind him, whip out my wand and shoot my magic all over his ass!
Stuart: Do you hear yourself when you say these things?

Raj: Ever since I saw Pretty in Pink, I've wanted to go to an American prom. But then I saw Carrie and did not want to go to an American prom. Then I saw Never Been Kissed and I'm back on the prom bandwagon. This prom things been a real roller-coaster.

Raj: Amy, good luck getting these guys excited about a dinner with a theme. I gave up when no one cared about my Tom Hanks-Giving.

Raj: Boy, I'm so hungry today. I wonder why.
Howard: Because you had sex the other night?
Raj: You know what, that might be it. By the way, it isn't like riding a bike. I fell off a few times.
