The star hit the headlines in 2007 after he appeared on the Mornings With Kerri-Anne talk show to promote ER, but stunned viewers by wandering around the set and slurring his words.
A spokesperson claimed Stamos was having difficulty adjusting to the time difference Down Under, but he insists his bizarre behaviour was actually the result of sleeping pills and alcohol he downed before the show.
He tells The Advocate, "I'll be honest: When I went on that morning show, I was drunk. Yes, I was on sleeping pills and I was jet-lagged, but I was also just plastered (drunk). And I never said I wasn't, but that whole Warner Bros. publicity machine got involved and said, 'Just say he was jet-lagged.' I said, 'No, tell 'em the truth! I was f**king drunk in Australia. Big deal.'"
And the actor admits the broadcast got him in hot water with an angry Australian reporter, who he accused of having "a small penis" while on air.
He adds, "I was mad at that guy because he put on a video from our (previous) interview, when it was early in the morning and I was dozing off, and he made it seem like I was on drugs, which was not true. My mother saw that and got really upset. So when I went on that talk show (Mornings With Kerri-Anne) the next day, I made fun of the guy by saying he had a small penis. He tried to sue me for that, you know. I said, 'The only way he's going to prove me wrong is to whip his d**k out in court,' so the lawsuit went away."
