Comical Nap Drool

From the storyboard of Frozen

If you have a character who is fast asleep, what would be a comical way to display this? Why don't we have the character trickle down saliva from his mouth, as in drooling like a little baby?

This is the trope where a character drools while sleeping is a noticable display of comedy. In some cases, drooling can be used to indicate innocence, since, commonly, small children tend to drool while they're asleep. When adults do this, it's supposed to portray them as inelegant and crude, especially with females. Then again, when women do it, it can be considered as cute while male droolers are considered to be very childish.

This can be justified by the fact they are a Heavy Sleeper. There's an indication that whenever a character drools at sleep, it shows that the sleeper is mentally dumb, and/or socially awkward (rarely Book Dumb). This could also happen if they're dreaming about food. Pretty much people do this at one point.

Examples:

Films

Literature
  • This appears in the first Percy Jackson and the Olympians book as a way to establish Annabeth and Percy's Frenemies -> Vitriolic Best Buds relationship. Annabeth is tending Percy after his battle with the Minotaur. He expects her to compliment him; instead, she says, "You drool in your sleep."

Live-Action Television
  • Mentioned, though not shown, in an episode of Buffy the Vampire Slayer.
    Buffy: Did anyone notice that I was asleep?
    Willow: Very discreet, minimal drool.

Western Animation
  • Patrick from Spongebob Squarepants does this occasionally, most especially in "Home Sweet Pineapple" where Spongebob had to spend the night at his house while his Pineapple Home was eaten by nematodes, absorbing all of the saliva coming out of Patrick's mouth.
  • Homer Simpson from The Simpsons:
    • In one episode a robber breaks in and the family is tied up while they're all in bed asleep and brought to the living room. Lisa looks at Homer drooling. "Oh, no, dad's been drugged!" Marge: "No he hasn't."
    • In another episode Homer thinks he has eaten some poison blowfish and has 24 hours to live. He stays up that night listening to The Bible on tape read by Larry King. Marge finds him the next morning and starts to weep - but then realizes "his drool! It's still warm! Oh, Homie!"
    • Another example comes from "Treehouse of Horror II", where Homer's brain is placed in a robot and the robot proceeds to sleep and drool oil.

Real Life
  • One of Dave Barry's columns features a related phenomenon when he's sick with the flu:
    "Another symptom is that you cease brushing your teeth because (a) your teeth hurt and (b) you lack the strength. Midway through the brushing process, you'd have to lie down in front of the sink to rest for a couple of hours, and rivulets of toothpaste foam would dribble sideways out of your mouth, eventually hardening into crusty little toothpaste stalagmites that would bond your head permanently to the bathroom floor."
