OTR: Do you have a fence?

Professor T: “It was the coldest day of the year and the pipes of my house burst. Trying to get a plumber to come to your house when the Vikings are playing the Superbowl? That’s a cold day in hell…”
Professor T: “Do you have a swimming pool?”
Student: “Yes.”
Professor T: “Do you have a fence around the pool?”
Student: “Well, we do now. We didn’t have a fence around our yard until we built the swimming pool.”
Professor T: “And why did you build a fence around the yard when you built the swimming pool?”
Student: “Because my dad’s a lawyer.”
