Here is a list of 20th Century expressions that Joe Biden should avoid. These expressions are the equivalent of an un-zipped fly.

Joe, don't ever say that you would blow something to smithereens. You don't need the 11 voters who know what the hell a smithereen is.

Never say that you are prepared to wait until the cows come home. Until hell freezes over is okay and besides, the cows are already home by now.

Quoting American historic figures is a campaign tradition. However, saying "as ole Strom Thurmond once said to me" would be the gaffe that broke the camel's back.

Joe, I wish I could have warned you not to refer to a record player in the last debate. I believe today they are called Victrola's.
