TRUE STORY:
A friend's dog was sprayed by a skunk this weekend. We went to the store to buy vinegar douche; I told him he could have just mixed vinegar with water but he insisted that the best way was to soak the dog down with douche, so he bought about 15 boxes.
We get to the check out with armloads of douche. As the checkout lady was ringing us up, he turned to me and said, "okay, you are going to have to hold her down because she's not gonna like this."
You should have seen the expression on the checker's face. Priceless.
