Throughout his career, T-Pain has been dogged by criticisms that he needs Auto-Tune in order to sing. Well, the self-described "rappa-ternt-sanga" showed the critics his vocal skills on the 'Arsenio Hall Show' Thursday night (Jan. 16).

Upon the request of the host, T-Pizzle sang an a cappella rendition of his chart-topping hit, 'Buy U a Drank' (Shawty Snappin'),' much to the audience's delight.

The Florida native then talked about his unique arrangement in his 11-year marriage with his wife. Apparently, the couple like to bring a third person in the bedroom.

"We involve other people in our marriage sometimes," he said. "Sometimes we have extraordinary partners and we like to travel around the world, go to different strip clubs... It keeps it real nice and fun."

During one of his strip club adventures, T-Pain made it rain in the club with 12 stacks ($12,000 for the uninitiated). "I picked most of it back up," he admitted.

Later, he entertained the crowd with a performance of his strip club anthem, ’Up Down (Do This All Day).'
