The "Two and a Half Men" star addressed at least one critic of his recent tumultuous behavior during the 50-minute presentation Saturday night, saying: "I'm in such a state of denial that I deny you exist," the Los Angeles Times reported.
The New York Daily News said about 100,000 people initially tuned in to hear what Sheen had to say, but many of the viewers had left by the time "Sheen's Korner" ended with him repeating the word "duh" over and over again.
"Guess what we were doing all day, every second of the day? Winning," Sheen said, displaying a tattoo of the word on his left wrist, the Daily News said.
"This was just sad, and boring and pointless," a viewer with the Twitter name Sasu Uzumaki posted.
Sheen's hit television show "Two and a Half Men" was suspended for the remainder of the season after he blasted his bosses in several interviews.
His alleged drug abuse and strange behavior resulted in a restraining order being granted to his estranged wife and the removal of his twin toddlers from his Sherman Oaks home.
