JASON CASTRO IS SCARED OF DOLPHINS!!

The American Idol contestants are in Las Vegas this week to drum up publicity for the final four, and the worst of the four Jason Castro continues to show why he's the weakest link... In this clip, he tries bonding with a dolphin, even shoving his dreads out of his face to steal a kiss, but is quickly spooked and runs away like a lil baby...

Seems nobody likes him but the dogs!! Have a look at this video from his high school where he's MAKING OUT with a dog... Ahhh!!
