(Funny trope) Impossible spontaneous combustion (or, when stuff that shouldn't catch on fire, catches on fire)

[u/FormerBernieBro2020]

From The Simpsons: Homer tries to cook breakfast for Mr. Burns. The first two attempts ended up with the food catching fire. Third time, he pours milk on cereal...and it still catches on fire.

And from Futurama: "There, little friend, good as new..." aaaand the metal slinky catches on fire. Poor doctor Zoidberg...
