Too Dumb to Live/Oral Tradition


 * There is a joke about a Dumb Blonde where she is found sleeping with headphones on. The others think she must have forgotten them on and helpfully take them off for her. Later she's found inexplicably dead. Turns out the tape she was listening to went "breathe in -- breathe out -- breathe in...".
 * A tale about a donkey who died of hunger between two equally big piles of hay.
 * Swedes and Norwegians have a whole genre of anecdotes depicting each other as this.
