->''One yodel out of place would attract, not [[Film/TheSoundOfMusic the jolly echo of a lonely goatherd]], but fifty tons of express-delivery snow.''
-->-- ''Discworld/ReaperMan'', by '''Creator/TerryPratchett'''

Someone in the mountains triggers an avalanche by shouting or making another loud noise (shooting a gun, detonating an explosion, [[SneezeOfDoom sneezing]]), especially if other characters have warned him about this before.
