From the movie "Grease:"

[Rizzo and Kenickie are making out in Kenickie's car, crawling into the backseat together]

Kenickie: Oooh, Riz... Riz...

Rizzo: Would you call me by my first name?

Kenickie: Ooohh, uhhh... ooohh... uhh...

Rizzo: Betty.

Kenickie: Betty, Betty... [says her name several times, in increasing passion]

Rizzo: Hey... ya got something?

Kenickie: Are you kidding? [Sits up and gets a condom out of his wallet]

Kenickie: My 25-cent insurance policy.

Rizzo: Big spender! [Kenickie opens the condom packet, is shocked as he finds it broken]

Rizzo: What?

Kenickie: It broke!

Rizzo: How could it break?

Kenickie: I bought it when I was in the seventh grade. [the two spend a long nervous moment considering the situation, but look to each other with growing lust]

Rizzo: What the Hell... [Rizzo grabs Kenickie, and they resume making out]

Kenickie: [muffled] Oh Betty...
