A blonde is watching a ventriloquist perform at a bar and the ventriloquist, with his dummy, is telling blonde joke after blonde joke, filling the bar with laughter. After several of these jokes, the blonde stands up, infuriated, and yells, "Listen here, jack*ss. Not all blondes are stupid and the jokes need to stop, it is a very cheap way to get laughs." Stunned, the ventriloquist timidly begins to apologize, "Ma'am, I am so sorry. I had no idea I was offending anyone." The blonde replies, "Stay out of this, sir. I'm talking to that little sh*t on your knee!"
