Ask for an interesting and instructive joke

A doctor was assigned to a research institute and became the person with the highest academic qualifications.

One day, he went fishing in the small pond behind his unit. It happened that the director and deputy director were around him and were fishing. He just nodded slightly. These two undergraduates have nothing to talk about. After a while, the director put down the fishing rod, stretched himself and walked briskly across the water to go to the toilet. The doctor's eyes are about to fall off. Floating on the water. No This is a pond. When the director came back from the toilet, he also floated back from the water. What happened? It is difficult to ask for a doctoral student because he is a doctoral student!

After a while, the deputy director also stood up, took a few steps and floated across the water to go to the toilet. Now the doctor almost fainted: no way, go to a place where Jianghu experts are concentrated. Doctoral students are also very anxious. There are walls on both sides of this pond. It takes more than ten minutes to go to the toilet opposite, and it's too far to go back to work. What should I do?

Doctoral students don't want to ask the two directors. After holding back for a long time, they got up and stepped into the water: I don't believe undergraduates can pass, but my doctoral students can't. The doctor fell into the water with a bang. Two directors pulled him out and asked him why he had to go into the water. He asked, "Why did you walk there?"

The two directors smiled at each other: "There are two rows of stakes in this pond. Because it rained these two days, the water just rose below the surface. We all know the location of the stake, so we can step on it. Why don't you ask? "
