Brain Bleach/Live-Action TV

Examples of the need for in  include:

Frasier
"Roz: Gosh, mine was this lifeguard. He had long blond hair and the bluest eyes. He used to get so sunburned, I'd spend hours just peeling the skin off his back. What was his name? Rick? Nick! I know there was an "ick" sound. Frasier: I was about to make one of those myself."
 * Frasier's reaction to his brother mentioning he's only packing sunscreen for his honeymoon.
 * Frasier makes many statements like this in the series. Another example:

"Roz: Big news. Gertie Oldson is leaving the station. Daphne: What, from "Gertie's Grab Bag"? I love that show. Frasier: Oh please, that homily-spouting Hausfrau? It's the most embarrassing thing on the air. So, she finally got canned, eh? Roz: No, she got a million-dollar TV deal. Frasier: (chokes on his sherry, then mock-calmly mutters) Well, good news for Gertie and for the many atheists who will welcome this new proof of their theory!"
 * "Roz's Turn":

"Frasier: (after seeing his mentor Dr. Tewksbury wearing only Roz's robe) I've gone blind. And ten seconds too late."
 * "The Wizard and Roz":

"Frasier: (reading the opening of Roz's new favorite romance novel) There are tangos that come flowing from the wine-colored seas, from the rust of a hundred sunken ships. This is one of those dances. Roz: Well? Frasier: There are books that make your stomach lurch, and rumble, and thrust your lunch ever upwards. This is one of those books!"
 * "Slow Tango in South Seattle":

"Waiter: Hey, where'd you get the nipple shot? Frasier: Good lord! Niles: (frantic) You are to erase that from your mind! Frasier: Is it Daphne? Waiter: (smiling broadly) Nice. Niles: (to waiter) You're not erasing! ERASE!"
 * In "Lilith Needs A Favor", Niles demands the Cafe Nervosa waiter use Brain Bleach to forget about what Niles thinks is a picture of Daphne's nipple.

"Martin: Oh, I can't wait to get to Bogart's. I know just what I'm going to get: the barbecue chicken breast. (Niles reacts in horror) They have the juiciest one in town. Or, or the lamb. They serve an enormous rack. (Niles cringes again) Niles: (flustered) Great. Martin: You might want to get an overcoat of Frasier's out of there. It's supposed to be pretty nippy tonight. (Niles cringes yet again)"
 * Later, Niles finds out that it's a pic of Martin's nipple. Niles' horror is hysterical as he tries to forget ever seeing the pic. Martin's poor choice of words doesn't help.

"Niles: [running for his bug spray:] Frasier, you didn't do anything wrong, your feelings for Mia stem from perfectly natural Oedipal desires. Frasier: Yes, but Oedipal desires are supposed to resolve themselves by the age of six! [Niles starts with the bug spray.] Frasier: Oh for God's sake, give me that, you idiot! [Frasier takes the spray and "blinds" himself with it accidentally.] Frasier: [screams] I've blinded myself! [Martin enters with water and sees the commotion.] Martin: I leave you alone with him for two seconds!"
 * The episode "Momma Mia" when Frasier finally realises that his girlfriend is identical to his late mother, and Martin thinks that he has further followed suit of Oedipus.

Okay, well, all right, I'd better go out to the woods and tame my dragon. Harry: Ah, you got a new pet? Hagrid: (pause) Nope."
