In the midst of hygiene upselling, we are bullied into buying antibacterial agents to ensure everything is clean. Who could take the ad with the hippy sneezing on the shopping trolley seriously? Soccer Mums, that's who.
Dave Allen once commented on fly spray: " 'Kills 99 percent of household bugs!', they say. What effect does it have on the 1 percent it doesn't kill? Feeds them? Makes them stronger? We're going to end up with superflies, invulnerable superbugs with the strength of a thousand ordinary bugs." Or something like that. Only now are scientists being able to demonstrate what comedians have observed for years. (Hat Tip BB)
