My pre-teen daughter explained spontaneous combustion as:

a random and sudden outburst of laughter
Suffering from spontanious combustion usually stems from nervousness or excitement.

Phenomenon in which any animal caught defacating on my lawn bursts into flames, and it wasn't my fault.
Bob: "Howdy neighbor! By any chance, have you seen my sweet little Sparky? He's been missing for two days now."

Jeffy: "Uhhh....uhhhhh....I didn't do it."

Bob: "What?"

Jeffy: "You're not gonna believe this: I was mowing my lawn the other day and...I smelled something...burning. I looked over to see poor Sparky engulfed in a ball of fire, yelping for help......but by the time I reached him he was utterly consumed and only his ashes remained. That's what happened to Sparky. I'm not lying, it was Spontanious Animal Combustion Bob."

Bob: ".............*gurgles*"
