I'm not sure why you're so focused on a one-day wobble, Neapolitan, when the graph I posted showed the overall trend of one famous stock-market indicator. Big picture, the day you're talking about isn't significant:-
As for the "windows" comment, I only posted it in haste to counterbalance a run of posts that suggested Biden was too senile to debate, or express himself. I just wanted to show that Trump was equally capable of talking nonsense.
Your quote from Biden about hairy legs was very funny and I wouldn't tie myself in knots trying to defend it. I'm not sure that Trump's ill-expressed anxiety about eyesight in five years time is worth defending either, tbh.
