Girls in pool with clothes on

I told Lindsey that if she said 'no' to me one more time, that I'd throw her into the pool with her clothes on (we were joking around). So, then I said to her, "Will you say 'no' to me again?" and of course she said, "No", before she realized that she actually said 'no'. So, I took her to the pool, and she was laughing all the way, until I pushed her in. She was FURIOUS!!!!!!!!!!!!!! I took great delight in seeing the disbelief in her face when I actually pushed her in. She thought I ruined her princess nightgown. Then, I told her that it was just water, and then she was fine. After that, I pushed Erin in, and they laughed hysterically for a long time. Then, they swam for about 2 hours in their clothes. I joined them, with shorts and a tank top. Now, they would like to have at least one day per year to swim with their clothes on. They thought it was such a treat.
