>> Dad called him a “sap”.
Love it!
Hee hee. Me, too! When a crooked leftist politician got his card handed to him, Dad would come forward in his chair and yell, “Kapow!”
And his usual insult directed towards a bad driver, rather than jacka_s, was “you Jasper!” Probably having children motivated him to use these expressions more often than the occasional expletive.
Good, old Dad.
