Pool party

It was the day before Rock's longtime friends Tom and Corky Zaluedek were moving out of their house, and they were about to host a pool party for the Little Rock Hash House Harriers.
Rock arrived early and had to urinate, but all of the bathrooms had been shut down or boarded up. He wandered to the back bedroom that Tom and Corky shared, where he found Corky alone. He asked her what he should do.
"Don't tell anyone, but we've been using the swimming pool," Corky said.
When Rock arrived poolside, he saw that the water was brownish and murky, as if it belonged in a farm pond. Getting into the water was out of the question, but the backyard was unfenced, and he was too self-conscious to simply pee into the pool from the side. There had to be another place.
