Deleted scenes for this episode include Michael talking about Ben Kingsley and Pam pointing out that Michael's shirt is buttoned incorrectly.

We find out that Michael and Carol have only been on nine dates since Casino Night. After Michael proposes to her, she leaves the party without him.

In this episode, Kelly's parents were played by Mindy Kaling's actual parents.

Michael: Tonight, one of our most ethnic co-workers, Kelly, has invited us all to a Diwali celebration put on by her community. 'What is Diwali?' you may ask. Well, to have Kelly explain it, 'It's, blah blah blah blah. It's so super, fun, and it's gonna be great!' Lot of gods with unpronounceable names. Twenty minutes later, you find out that it is essentially a Hindu Halloween.

Michael: And another thing about the Indian people, they love sex positions. I present to you the Kama Sutra. I mean look at that. Who has seen that before?
Creed: I have. That's the Union of the Monkey.
Meredith: Oh, that's what they call it!
Kevin: This is the best meeting that we have ever had.
Michael: Thank you, Kevin.
Angela: You know, I find this incredibly offensive.
Michael: Well, I find it beautiful.
Angela: Well, whatever Kelly wants to do in her own house is fine, but we shouldn't all be subjected to it.
Toby: Actually, she's right. This is inappropriate. Why don't I take these.
Michael: No, you're not going to collect them-
Toby: Yeah...
Michael: No! This is delightful, charming culture.

Pam: It's hot in there. How's the naan?
Angela: Dry. You look like you were having fun.
Pam: I am. You should come dance with us.
Angela: I have to watch our shoes, so they don't get stolen.

Karen: Hey dummy! Get in the car!
Jim: I'm a drunk driver.
Karen: Yes you are.

Michael: Carol? Carol Stills? I would like you to do me the honor of making me your husband.
Carol: Oh... Michael.
Michael: What do you say?
Carol: Can we talk about this in private?
Michael: I didn't hear you.
Carol: (louder) Can we talk about this in private?
Michael: (whispering) Oh, you've got to be kidding me. Okay. (drops microphone and walks away)

Michael: Apu, from The Simpsons. Hilarious Indian.

During his slideshow, Michael makes a reference to the only Hindu character on The Simpsons, Apu Nahasapeemapetilon.

Andy: Rollercoastery friendship. Hot and cold. On again, off again. Sexual tension-filled type of deal. It’s very Sam and Diane.

Andy is referring to the 1980s sitcom Cheers, and two of its main characters, Sam Malone and Diane Chambers.

Ryan: They said something about Zach Braff.

Ryan thinks Kelly's sisters were talking about Zach Braff, from the fellow NBC comedy Scrubs.

Michael: (singing) So put on your saris... it’s time to celebrate Diwali... Everybody looks so jolly... but it’s not Christmas, it’s Diwali...

Michael's Diwali song is a parody of Adam Sandler's popular "Hanukkah Song."

Angela: Don’t go, they eat monkey brains.

This is in reference to the film Indiana Jones and the Temple of Doom where the Indians serve chilled monkey brains for dessert.

Andy: (singing) I went to the doctor, I went to the mountains, I looked to the children…

The song that Andy (and later Jim) sings is "Closer to Fine" by The Indigo Girls.

Michael: This is just like that show, Taxicab Confessions.

Taxicab Confessions was a documentary show that aired on HBO, where unsuspecting cab patrons were recorded talking about their personal issues with taxi drivers.

Meredith: (to Pam) Do you wanna make appletinis and watch Sex in the City at my place?

Meredith is referring to the popular HBO series, Sex in the City, starring Sarah Jessica Parker.

Dwight: I see dead people.

This is a line from the 1999 film, The Sixth Sense.

Visual: Michael's two-headed costume

The costume Michael is wearing as he and Carol walk into the Diwali celebration was first seen in the Season Two episode, "Halloween."

Andy: Tuna?! Are you kidding me?!

This is a reference back to the earlier Season Three episode, "Gay Witch Hunt," where Andy nicknames Jim "Big Tuna" because of the tuna sandwich Jim brought for lunch.
