My dad is a dentist, and when I was little I was snooping in the bathroom cabinet when I came across a bottle of fancy mouthwash, designed to fight infection, which was labelled "Oral Rinse". My little mind must have been in the gutter, for I thought it was something like an enema. For a couple of years I misunderstood the difference between "oral" and "rectal".
