Charlie Sheen Keeps Winning, Rolls Into 'Conan' in Military Tank [Video]

Charlie Sheen's not only winning, he's indestructible. At least he was for a minute, when he rolled back onto the Warner Bros. lot for the first time in more than two years -- this time in a military tank with two "goddesses" in tow -- to plug his new movie "Scary Movie 5" on "Conan." Sheen was famously banished from the WB lot in 2011 after his notorious and extended public meltdown, which got him canned from CBS's cash cow "Two and a Half Men" by fed-up executive producer Chuck Lorre.

His highly publicized meltdown all began when the erratic star was rushed to a Beverly Hills hospital following a drug-fueled sex-capade with a slew of porn stars in January 2011. He followed that up by trashing a suite in New York's Plaza Hotel. Shortly after, during an interview with ABC's Andrea Canning, he said, "I'm bi-winning," as a response to her suggestion that he's bipolar. He also famously said, in one of the many interviews that followed, "I am on a drug, and it's Charlie Sheen!"

After he was fired from "Men" -- and we mean right after, as in later that day -- Sheen made his way up to the rooftop of the Live Nation building in Los Angeles, Calif., waved a machete, chugged a bottle of "tiger blood," and yelled, "Free at last!" Well, he's not famous for his subtlety.

He later told TMZ, "It is a big day of gladness at the Sober Valley Lodge because now I can take all of their bazillions ... and I never have to put on those silly shirts for as long as this warlock exists in the terrestrial dimension."

Now, Sheen is back and significantly more coherent. And despite evidence to the contrary (i.e., the tank), he is glad the war between him and the studio is over. "It's pretty exciting. I'm very excited," he said about being back on the lot, insisting that he doesn't have any mixed feelings. But his re-entry had its challenges: "When we pulled up to the gate, they ran like a really intense security check. Not that intense, but I used to be able to just cruise on in. Not anymore," he said jokingly.

How does Sheen deal with his anger now? By taking a bat to a watermelon-filled duffel bag and imagining that "a Warner Bros. executive hugging Chuck Lorre" are inside. OK, maybe all that bad tiger blood isn't water under the bridge just yet.

Over the past year, Sheen has taken another troubled and notorious superstar under his wing: Lindsay Lohan. Not only are they starring in "Scary Movie 5" together (they met on the film's set) and did they look mighty cozy on the film's red carpet Thursday night, but she had a guest spot on his hit FX comedy, "Anger Management," which also aired Thursday.

Lohan apparently stuck to her MO, arriving a reported 45 minutes late to the "Scary Movie 5" red carpet. Sheen recently commented on LiLo's tardiness tendencies on "The Tonight Show" (confirming a report from an on-set source, who said Lohan held the cast and crew "hostage") by saying, "It was as though she had us held hostage, because she gave us half the show. … She was a couple of hours late. She was really not feeling well. We just worked around it."

Will she be back on "Anger Management" despite her presumed diva antics? It's possible. Sheen told "Extra's" Terri Seymour that LiLo impressed him on the set of his FX show, adding, "She can do an arc. She can come back. Whatever she wants."
