Thousands of students were gathered together in green for a “St. Fratty’s Day” party at California Polytechnic State University. In the video you can see many people standing on roofs, exemplifying the poor judgment of drunken college students. That’s all fine until one roof just couldn’t take the weight and crashed to the ground, taking several unlucky students with it.

And here’s a better angle of the collapse:

According to FOX6NOW, everyone is ok, but one person sustained a particularily nasty injury:

The city said in a statement that in the most serious injury, a person’s thigh was impaled by a piece of debris early Saturday. At least seven others were treated for cuts and bruises. None of the injuries are life-threatening.
