Celebrities are often ridiculed for being clueless about the world issues, thinking that the world revolves around them and no one else.

On the other hand, blond girls are also made fun for being thickheaded and air-heads.

Anyone hear the joke about why the blond stared at the carton of orange juice?

Well, this story is the best of both worlds, as the 32-year-old Paris Hilton, while her 21-year-old boy toy River Viiperi was strapped down to an ambulance stretcher, the hotel heiress posed for a snowy photo and posted it to her Twitter account.

Earlier this month the socialite and her model boyfriend vacationed in Lake Tahoe for her birthday. While hitting the ski slopes, Viiperi took a nasty tumble, gashing his leg and needing to be hauled away by paramedics, reported New York Daily News, and instead of being by his side through the ordeal, Hilton decided that it was a great opportunity to pose with her famous pout for the cameras.

"Such a scary day on the slopes today.' Hilton wrote on her Twitter page, with her boyfriend gives the camera a thumbs-up in the background.

Adding, "After seeing the gash on @RiverViiperi's leg, I almost passed out. I have never seen a cut that deep in my life. He is so brave, I can't even imagine the pain he went through today."

Viiperi, showing how fine he was by actually posting a picture of his leg, while cuddling up with the "Simple Life" scarlet.

"I had to stick my leg yesterday because of what happened to me while we was [sic] skiing," Viiperi said via Twitter. "But I'm better now thanks to my lovely @ParisHilton who always taking such good care of me."

There is another joke to be made there, but will be left alone.

By the way, for those who haven't heard the aforementioned joke--the carton said concentrate.

If it doesn't make sense, you are probably blond.
