It's sad, but the late "Jackass" star Ryan Dunn's greatest legacy might be as an anti-role model. The daredevil, whose Porsche is said to have been traveling between 132 and 140 miles per hour when it crashed last week killing Dunn and passenger Zachary Hartwell, had a stunning blood alcohol content of .196, according to a preliminary toxicology report. With an estimated 11 drinks in him before he got behind the wheel, he automatically becomes the poster celebrity for what can happen to you when you drink and drive.

Indeed, Roger Ebert's notorious tweet — "Friends don't let jackasses drink and drive" — over a photo of the horrific remains of that car could serve as an effective public-service billboard. Recent years have, unfortunately, brought us a phalanx of anti-role model celebrities — who teach us by example what not to do.

Two years after Michael Jackson's death of acute propofol intoxication, his doctor, Conrad Murray, is due to go to trial in September on involuntary manslaughter charges. But certainly, the details of Jackson's gargantuan prescription drug usage that set the stage for the overdose have given people pause.

The same is true of Heath Ledger, who seemed destined to become one of the greatest film actors of our time, until his life was cut short by what the New York City coroner's office determined was an accidental overdose of painkillers, sleeping pills and anti-anxiety drugs: oxycodone, hydrocodone, diazepam, temazepam, alprazolam and doxylamine.

Look out, because, as the late Jeff Conaway pointed out, getting addicted to pain pills can creep up on you. Lindsay Lohan and Charlie Sheen are just two among the current crop of celebrities who have all but destroyed their careers with wild and sometimes violent behavior — behavior that has landed each of them behind bars more than once. Lohan and Sheen have each demonstrated how even the most prodigious talents can be thrown away — let us hope not their lives. Their poster would have to say something along the lines of: "Here's what excessive partying can do to you, kids."

Anti-role model celebrities show us so many things — how not to divorce (e.g. Madonna and Guy Ritchie), how not to parent (Britney Spears) and how not to utilize cosmetic surgery (Joan Rivers).

ON THE CUSP: Nickelodeon hasn't even launched their "Bucket and Skinner's Epic Adventures" series yet, and already teen stars Taylor Gray and Dillon Lane are getting their first tastes of fame, going out and being recognized by fans. "We were surprised. They know about our show before it's even aired," notes Dillon, who plays carefree surfer Skinner on the series, which debuts July 1. "Of course, that shows Nickelodeon is doing a good job of advertising it, and we're also lucky enough to have some friends with successful shows who are giving us some help."

"Ashley Argota of 'True Jackson, VP' is actually in the cast of 'Bucket and Skinner,'" Dillon adds. "She has a very big Twitter following, like, 90,000 followers, and she's helped us."

Taylor says the subject of fame has definitely come up around the set. MTV expects good things. The network saw the first few "Bucket and Skinner" episodes and upped its order of the show from 13 to 26. Has he thought about dealing with fans, press, parties, etc.? "I should probably put more thought into that," answers the actor who plays the relatable everyday high-schooler Bucket. "Everyone's talked to us about it. But no matter what you hear, it's hard to know what to expect. There's always that aspect of it — the unknown. It's pretty crazy to think about, to be honest. As long as I continue to be the person I am, with my same close friends and my family, I think I'll be OK."

Says Dillon, "I've definitely thought a lot about it. With all the cool opportunities and, hopefully, the success I could retain from this series, if I'm lucky enough to gain a voice, I'd like to use it to help people. That's one of my goals." OK, they're adorable. Let's see how they are in five years.

INDUSTRY BITS: Jason Priestley is getting ready to direct "The Legend of Buckout Road," a chiller about a crew of stoned filmmakers and teenagers who go out looking for the location where a creepy murder took place. They're hiring actors for "It Takes a Village," a reality TV-style documentary that has to do with families who have reached the end of their ropes with their teenagers' bad behavior. The producers are said to be planning something positive and uplifting.
