Anyone can make a mistake...

... but to really f*** up, you need a computer:

Earlier this month, about 17,000 students were offered admission [to the University of California at San Diego] for the fall, leaving nearly 29,000 hopefuls out in the cold.

But on Tuesday, the school's communications office said an e-mail was sent Monday afternoon to all 46,377 students who applied for admission -- including the 29,000 rejects -- welcoming them to the campus.

A half-hour later, school officials said, they realized their mistake. Almost two hours after the first note went out, a second e-mail was sent, apologizing to 28,889 freshmen applicants for the mistake.
