You can't make this shit up: Biden makes a bizarre joke about his uncle eaten by cannibals, a reporter asks why Biden does that, Biden's Press Sec scolds the reporter for making a joke about Biden's joke and... blames Trump.
Without his teleprompter, Biden can't complete sentences jumping between lies & thoughts, makes long pauses and diluting his incoherent mumbling with "not a joke," etc. Doctor Jill is trying to direct him.
