YouTubers are fretting about Denver Nuggets NBA player JR Smith's costly mistake (and one of the oddest events ever in US professional basketball according to commenters) of inbounding an air ball by Sacramento Kings player Tyreke Evans.

Meanwhile, Mariah Carey seemed out of sorts when she accepted an award at the Palm Springs Film Festival, with the video of her drunken speech generating almost two million views.
