WATCH: MSNBC’s Krystal Ball Pranked Over MH17 Crash

MSNBC’s aptly named Krystal Ball was pranked by a caller who pretended to have been a U.S. military witness to MH17 plane crash in Ukraine. After questioning the “witness” about what he saw, the man tells her the plane was brought down by “wind from Howard Stern’s ass.”

Then, amazingly, Ball tries to ask the caller more questions about “missile systems.” Eventually, the interview comes to a crushing end when he calls Ball a “dumbass.”
