As for yesterday's Michael Jackson hoopla, I offer you "ersatz": being a usually artificial and inferior substitute or imitation.

Useful synonyms include faux and knock off.

You may also consider "The President's Speech" from The Man who Mistook his Wife for a Hat by Oliver Sacks, 1985, about a ward of aphasiacs and agnosiacs listening to and laughing at a speech given by an unnamed actor-president, "the old Charmer," presumably Ronald Reagan. For, 'one can lie with the mouth,' Nietzsche writes, 'but with the accompanying grimace one nevertheless tells the truth.'
