The forfeit is sometimes described by panellists as a "klaxon": in "Knees & Knockers", one of the questions addresses this. It is not a klaxon, as this is a specific brand name owned by Lovell-McConnell Manufacturing; "siren" was suggested as an alternative description. Most forfeits deprive the contestant who caused it of 10 points. Some forfeits can take away more points: for instance, in "Atoms", the forfeit "carbon dioxide" would have scored -3000 points, although nobody said it.
