Being vice president is a bitch.

Says who? Vice President Joe Biden!

A student at Harvard University identified himself as vice president of the student body as he tried to ask Biden a question at a forum.

“Isn’t that a bitch,” Biden said with a grin. “I mean . . . excuse me. The vice president thing.”

The students laughed and applauded Biden’s salty remark during a Harvard Institute of Politics event Thursday evening.

Biden — often ridiculed for his tart tongue — quickly made clear that he was kidding around and that he really liked his job.

“Wow. I’m joking. I’m joking. That was a joke, best decision I ever made,” according to a CNN video and report.

The startled student said he hoped that Biden liked his job.

“I love the guy I work with,” Biden said, referring to President Obama.
