Men are such perverts that they even ejaculate in their sleep. There is a perfectly normal (i.e. non-perverted) biological explanation for this, but Fiction Land likes to pretend that it's always a result of an Erotic Dream and/or A Date with Rosie Palms. Also, in Fiction Land, women never do this. (In real life, they do, but barring female ejaculation it's a lot harder for women to tell in the morning.) Truth in Television for both sexes, though this phenomenon is more the exception than the rule. If a man is discovered to have such an emission by someone else (especially his Love Interest), he will Never Live It Down. See also Raging Stiffie and, as a natural consequence, Jizzed in My Pants.

- In Lamb: The Gospel According to Biff, Christ's Childhood Pal, Jesus heads to the East accompanied by his friend Biff to find the 3 wise men who came to witness his birth so he can learn how to be the messiah. The second of the wise men turns out to be a Buddhist monk who is the head of a Shaolin-esque monastery. While staying at the monastery, the two are naturally forbidden from being involved with women, or masturbating, and the only emission of semen can be involuntary, nocturnal ones. Biff, being a natural born lecher, promptly learns how to force himself to have dreams that will result in nocturnal emissions. Since they stay at the monastery for several years, he notes that he got pretty good at it.

- In The Sarah Silverman Program, Jay was in bed with Laura when she discovered he'd had a nocturnal emission. She found it so romantic because she thought this was because he'd dreamed of her, when it was in fact over the local news reporter.

His girlfriend sees this and gets mad and he tries to get the news people to let him apologize. On Live TV. Then his girlfriend forgives him and when the news people actually let him apologize, she burst in, onto live TV, and delivers (in a manner not unlike a PSA) a small speech about how nocturnal emissions are involuntary and they and the dreams are not under the control of the person who has them and shouldn't be held against them.
- The Daily Show - John Stewart, in response to a Rush Limbaugh sound bite of accusing Obama's immigration policy to be "a dictator's wet dream", had this to say:
