"Never floss with a stranger"

In this quote, Joan Rivers is using humor to communicate a serious message about personal hygiene. By stating "never floss with a complete stranger," she is stressing the significance of just utilizing your own floss and not sharing it with others. This is since flossing is a very intimate act that involves eliminating food particles and bacteria from in between your teeth. Sharing floss with a stranger might potentially expose you to their germs and put your oral health at risk. Rivers' witty and lively tone in this quote works as a suggestion to prioritize our own health and not take unnecessary dangers.
