Des gaffes et des dégâts
André Franquin
 In this album, Bertrand Labévue and the Gaffophone appear for the first time. Most of the gags are caused by the instrument. *filter for gases: to be placed on the exhaust pipe of one's car to prevent CO2 emissions *a rocket to modify the weather: rocket full of explosive, but inefficient *quick floor polisher: consists of an old fire extinguisher. *table : a table camping which can fold automatically, thank to a small button situated at the center of the table, which can cause some unexpected and accidents
