Problem: Extract the answer to the question from the following context. Question: Where did Kerry reference Bush? Context: Kerry said that he had intended the remark as a jab at President Bush, and described the remarks as a "botched joke", having inadvertently left out the key word "us" (which would have been, "If you don't, you get us stuck in Iraq"), as well as leaving the phrase "just ask President Bush" off of the end of the sentence.
