These commercials from Virgin Mobile actually advertises from a Yandere's point of view. She's seen sitting in a tree outside his house on a stormy night and talking about how they just had the best first date ever and she can use her phone to check on whether he's mentioned her yet and if his exes are hotter than her and that she can "check his Four Square profile for patterns." "And it's only $x a month! That's crazy right!?" *horror lightning*
In fact there is a sequel to this ad featuring the same girl in the guy's closet. . . .
Listen to the names. They're different guys. Fridge Horror kicks in.
What makes it worse is that if you watch Supernatural you'll realize that the actress playing her also plays Lillith, the psychotic demon who is also Yandere for Lucifer.
The Simpsons fan-created character Mara Morrigan, originally from unfinished fanfic "Bart Simpson's Obsession" but since then appearing in other works by various fans, is the sweet-seeming but secretly Ax Crazy cutie with an unrequited love for Bart.

The most popular fanon OC of Scotland is this (To a level that makes Russia look like Italy). Really, Half of the artwork is of him raping, or hurting England with a complete deadpan.
A large part of Christopher Titus' act revolves around the fact that his ex-girlfriend/ex-wife was this. As he put it at one point, when walking through the mall, he had to keep his eyes shut, or she would accuse him of eying and considering cheating with any woman he saw (including mannequins and fat men who look like they have breasts). He mentioned a situation with his new girlfriend that ended with her pulling an "inspected by #31 sticker" out of his underwear and laughing at him, whereas his previous relationship would have ended with her demanding to know who inspector #31 was.

Similar to TsundereCDs is the Yandere no Onna no Ko series, which puts the listener in the role of the onii-chan brother of a Clingy Jealous Girl. And by "Clingy Jealous Girl" we mean "girl who goes well off the hook because her brother has been spending time with women besides her."
In the vein of the Yandere no Onna no Ko dramas, listed above, there are also Yandere Heaven dramas, which set the (presumably female) listener in various situations (friend, assistant in a hospital, sister, etc) with two male yanderes vying for your/her affection.
