Joe Biden (D) (remember him?) our clean and articulate vice president, apologized to Supreme Court Chief Justice John Roberts for joking about the latter's mistake when he administered the presidential oath of office to Barack Hussein Obama (D).
Biden was to swear in senior executive staff at a White House ceremony after having already given the oath to newly confirmed Cabinet secretaries. When Obama reminded him that he had only done the one group and hadn't done the second yet, Biden quipped, "My memory is not as good as Chief Justice Roberts'."
You're right Joe, it is worse; you've forgotten the manners your parents surely taught you.
