The 30 Rock star stunned viewers with the comment about the former Alaskan governor during his appearance on the Inside The NBA broadcast on Thursday (27Jan11).
Host Charles Barkley asked the funnyman, "Sarah Palin's good looking, isn't she?" prompting Morgan to reply, "Now let me tell you something about Sarah Palin man, she's good masturbation material. The glasses and all that? Great masturbation material."
Turner Network Television officials were flooded with complaints and have now apologised for any offence Morgan may have caused.
A spokesperson says in a statement, "It's unfortunate Mr. Morgan showed a lack of judgment on our air with his inappropriate comments."
