Leonard: What for? It's not going to rain.
Sheldon: I know that, but with skin as fair as mine, moonburn is a real possibility.
Howard: [beat] That's a bazinga, right?
Sheldon: One of my best, don't you think?
Howard: [beat, laughs nervously]
For the sake of funny, a character goes out on a nice, peaceful night. But oh no; they forgot their moonscreen! Now they'll get a severe moonburn and then they'll be in real-trouble!
Moonbathing is a pretty common practice among weirdos and nightowls, and fiction usually portrays it as being just like sunbathing.
The moon itself only gives off 7% of the sun's harmful rays, but some characters have a bad habit of getting burns or worse when exposed to it for too long, and there always seems to be a cream to protect themselves from it. Fewer examples even suffer from the same affliction with other natural phenomena, from clouds to planetary alignments and other such wibble-wobble.
- In the beach-scene in Hotel Transylvania 3: Summer Vacation, Eunice Frankenstein asks her husband to rub moon screen on her back to prevent moonburn.
- In Krampus: The Yule Lord, when Krampus steps out of his cave into the moonlight for the first time in centuries, his skin immediately goes from a sickly pale tone to a dark-grey tone, almost as if his skin tanned in seconds.
- The Trope Namer comes from The Addams Family episode "Portrait of Gomez", where the family enjoy a nice quiet evening outside. Because Uncle Fester ate the moonscreen instead of applying it to his skin, he got a moonburn (apparently).
- In the iCarly episode "iStakeout", Freddie manages to get out of swimming with his crazy, overbearing mother by claiming that he did not want to get "cloudburn." Oddly enough, she does eventually find cloud block.
- The page quote comes from "The Lunar Excitation", an episode of The Big Bang Theory, in which Sheldon and his colleagues prepare to bounce a laser beam off of a mirror placed on the surface of the moon by Neil Armstrong in 1969.
- Intended as a plot point in an episode of Farscape: Blue-eyed members of a species on a particular planet suffer severe burns when both of the planet's moons are full. The victim of a murder supposedly carried out by Zhaan was one such individual, and the murder occurred on the night of a double full moon. The full version of the scene in which Chiana cross-examines another blue-eyed member of the species as a witness, one of the police officers involved in the arrest and who got a severe moonburn as a result, lead to her pointing out that even though the victim was found outdoors, he was not burned. This cast doubt on the state's case, as it indicated the man was killed elsewhere and moved. However in the final version of the episode that aired ("Dream a Little Dream") the fact that the victim was blue-eyed and wasn't burned by the moons was cut.note
- Vampire: The Requiem has a Vampire Variety Pack of whom the Mekhet Clan are especially vulnerable to fire and sunlight; a rare few are so sensitive that a clear full moon will give them a slight burn.
- Dungeons & Dragons has the moonbeam spell, which affects creatures sensitive to the light of the Moon, like lycanthropes.
- Peter Griffin from Family Guy has a hairless twin who lives in a storm shed in total darkness. When Peter goes to visit him at night, his hairless twin cringes and says, "Close the door, the moonlight burns!"
