As Sebastian Bach launched into a performance of Skid Row's 'I Remember You' on Sept. 10, 2011, the vocalist noticed a little problem within the Raleigh, N.C. crowd. As you can plainly see in the video above, an audience member was flipping Bach the double-bird; and as you can see, the singer struck back.

After calling a security guard over, Bach unceremoniously kicked the man out. "Come here, motherf---er! Get the f--- out of here! I want this guy to get the f--- out of here. F--- you! F--- you! Goodbye! Get him out! You're a f---ing a--hole! F--- you! Get him the f--- out of here, otherwise I'll get him the f--- out of here!"
