President Obama -- Upstaged by 'Angry' Key & Peele Star

Barack Obama made, arguably, the best decision of his presidency when he jacked a "Key & Peele" skit for his standout moment at the White House Correspondents Dinner.

If you missed it -- 'cause like most Americans, you don't watch CNN or C-Span on Saturday nights -- the prez brought out 'K&P' star Keegan-Michael Key to play his "anger translator" ... who says what POTUS is really thinking during speeches.

The bit always killed ... like it always does. Check out the pot shots at the media (including the W.H. Correspondents), Ted Cruz, and even Hillary Clinton.

Good move, B.O. ... leave the comedy to comedians.
