First rule of waking up on April 1: ABS. Always be skeptical. Especially if you're a TV newscaster. On this rain-soaked pranksters' holiday, Matt Lauer tricks co-host Ann Curry on the Today show, Mika Brzezinski refuses to fall for the old you-gave-me-yesterday's-script gag, Martha Stewart skillfully freaks out a producer by falling ill live on the air, and Kathie Lee Gifford and Hoda Kotb attempt to stay straight-faced while being entertained by the world's worst magician. Watch them all in our compilation above.
