Tracy Morgan slammed for over-sexed remarks about Michelle Obama

30 Rock actor Tracy Morgan has come under attack for his most recent ‘inappropriate’ detailing of his sexual attraction to US first lady Michelle Obama.

Morgan called the stylish wife of US President Barack Obama a "beast," adding "Michelle looks like a tall mountain...I'm gonna climb it just cos it's there" on the Lopez Tonight show Monday.

"Michelle [Obama] said, 'Hi Tracy,' and I just like, I got hard," the crude comedian shared about meeting the first lady at the White House Correspondents' Dinner last summer.

"Woah the #american people are collectively pissed off at Tracy Morgan," one Twitter follower wrote Wednesday, with another critic tweeting Morgan is "undeserving of the privilege of meeting the first lady, reports the New York Post.

Morgan previously drew criticism after describing former Alaskan governor and vice-presidential candidate Sarah Palin as "good masturbation material".

He even went to describe her as "the hottest MILF in the world" during a red carpet interview at the Screen Actors Guild awards.

Morgan also drew criticism in 2009 when he joked about the possibility of the ‘first White House sex tape’.
