In the UK there was a well known cream cleanser called "Jif".

The obvious implication was that it cleaned in a jif or jiffy - that is to say in a short period of time.

It has been re-named "Cif" (pronounced "sif").

"Sif", more properly spelt "Siph" or "Syph", is the colloquial diminutive for syphilis.

What genius names a cleaning product after a sexually transmitted disease?
