Biden’s potty mouth goes on display during surprise 9/11 stop in Shanksville, Pa.

Vice President Joe Biden’s potty mouth was once again on display during a surprise visit to a Shanksville, Pa. firehouse near where United Flight 93 crashed on 9/11.

Biden arrived just in time to crash the Shanksville Volunteer Fire Department’s members as they were having a barbecue.

The Vice President encountered Deputy Chief Brad Shober, whom he had met last year when he hosted the department at the Vice President’s residence in Washington at last year’s 9/11 anniversary.

“He’s going to call you, no bulls**t,” Biden said before noticing the pool of reporters following him before saying to them, “I didn’t know you guys were here.”
