In regards to celebrity, I have no idea who Ebert is. He's famous in America, but not really outside of it. My FB page lit up when Ryan Dunn died.
I knew who Ebert was since I was little - I'm 35 now (weren't those 2 Muppet characters sort of fashioned after Siskal & Ebert?). If you said "Ryan Dunn" without saying he was some guy in the Donkey movies, I would have no idea who you were talking about... Even then, I still wouldn't recognize him in public.
Quite honestly? I too am 35 and I knew who Ebert was since, well as long as I can remember. I had no idea who "Ryan Dunn" was when FB started exploding with "RIP" status'... and I've seen all the Jacka$$ movies, and in fact was just watching the show (repeats) over the weekend.
And further, when I did realize who Ryan Dunn was, and how he died my first reaction? The very first word out of my mouth? "Jacka$$..." as I wasn't meaning the show - I was meaning the guy. Because it is a JA thing to do.
I'll come out and say it - I have driven drunk. I've done it. I own it. And I know I was wrong. And very lucky in that I never got into any accidents. And I don't do it anymore, ever (not that I did it with any regularity). It took one friend getting pulled over and getting a DUI and the legal hassle of loosing her license, being banned from bars for a few months, etc, and we all cleaned up our act. We all realized the cost of a cab - heck the cost of 8 roundtrip cabs (so one r/t a weekend per month) - was not even a fraction of the cost of drunk driving, even if no one is harmed.
Ryan Dunn was famous not just for doing crazy stunts, watch YouTube there are billions of idiots out there, Ryan Dunn was famous for getting paid to do crazy stunts. He had more then enough opportunity to hire a cab, or a driver, or to limit his drinking to hotels, etc. He made a conscientious choice to not do so. And his friends made that choice too. And now, due to all their choices two of them are dead.
If even one of his friends at the bar that night had made a stand, had spoken up loudly enough, "hey jacka$$ call a cab!" Ebert would not have even had the opportunity to make the tweet to begin with. But none did.
But you know what? I bet at least once, if not about 100,000x times going forward, now, someone at the end of a night will drunkenly call out to their friends "Hey jacka$$, call a cab!" across a bar and yeah the bar might erupt in dispute about Ebert, or just discussion of Dunn, but a cab will get called and lives will be spared.
