Biden would lie about the weirdest things, such as his uncle getting eaten by cannibals. Except that his uncle's death in WWII is a verifiable and reported accident. His uncle did die in a plane crash in WWII on land though. Yet at the same time, he would tell the truth about very important things like "Nah, I better not say, I'll get in trouble" or bragging about "I called the Ukranian prosecutor and told him he better drop the investigation otherwise Ukraine won't get a billion dollars".
