Urinating During Online School Team's Meeting-OOPS

During an online class, a student decides to relieve himself and pee loudly into a toilet. Listen to the audio, and try not to laugh. The teacher does a good job of keeping a straight face and acting as professional as possible. How would you have reacted in the situation?
