Satire:
Dr. Jill has given the White House Staff a standing order that the president is never, ever to be given or allowed to handle anything that might produce a fire.
Joe is too forgetful and clumsy. Too many brain freezes to take a chance.
He almost burnt up her entire wig collection when he was VP.
Good thing Jill had a full bottle of champagne in the bedroom!
That would be an accelerant.
