Putting A Break In The Toilet Break

(We go on a school trip to the science center to listen to a lecture. Everyone is about 11 years old. After a while the lecture becomes boring for us and people start excusing themselves to the toilet to get out of it. A teacher suddenly disrupts the lecturer and yells out:)

Teacher: “None of you are little kids anymore! I’m pretty sure most of you have complete control over your bladders. So let us extend our condolences to those who keep going to the washroom because apparently they seem to have some extreme bladder problems and now everyone knows. The poor things. Now the rest of you with proper functioning bladders, HOLD IT.”

(No one went to the toilet after that, even if they really had to.)
