Euphemism Buster

Someone uses a euphemism, Last-Second Word Swap or something similar, and someone else blurts out exactly what the first person meant.

It generally comes in two versions: Ditz and Intentional. Ditz version is just the person figuring it out for himself. Intentional being the euphemism is too insulting/obvious or the character simply doesn't care, and so busts the euphemism.

The euphemism may or may not be unusual. Compare and contrast Lampshaded Double Entendre, Don't Explain the Joke.

 * On Chappelle's Show, a parody of a PBS Frontline documentary has the narrator (a white man) warn viewers:

"Sally: He said he wanted to sleep with me. I wanted sex, but seeing as he was tired I decided to just go home."
 * A variant from an episode of 3rd Rock from the Sun:

"Mayor: No slayer of mine is going to live in a fleabag motel. That place has a very unsavory reputation. There are immoral liaisons going on there. Faith: Yeah, plus all the screwing."

 * From Mallrats:

"Shenzi: Yeah, be prepared! We'll be prepared! For what? Scar: For the death of the king! Banzai: What, is he sick?
