Howard Stern Calls Jay Leno 'That Dummy' On 'Late Night' (VIDEO)

Howard Stern calls Jay Leno "that dummy" on "Late Night"

Howard Stern has made no secret of his loathing for "Tonight Show" host Jay Leno. On "Late Night" (Weeknights, 12:37 a.m. ET on NBC) Thursday he attacked Leno again, calling him "that dummy."

Stern went on the offensive after he discovered that host Jimmy Fallon had asked both him and Leno for advice on interviewing President Obama.

"What a mistake," said Stern. "That dummy. ... You called Jay Leno? Jay Leno hasn’t done a good interview ever!"

Stern's previous talk show attacks on Leno have included calling him "a crook" and saying that he's "horrible."

The "America's Got Talent" judge also insulted Fallon's musical guest, former Rolling Stones guitarist Mick Taylor, but later apologized to him on Twitter.

"America's Got Talent" Season 7 premieres on Monday, May 14th at 8 p.m. ET on NBC. "Late Night With Jimmy Fallon" airs weeknights at 12:37 a.m. ET on NBC.
