The Ant and Toothpick

I did Grade 10 twice. Once in Dubai and due to the timing of the course and all I had to do 3/4 of Grade 10 again in K.L.

My school in Dubai was a very disciplined school and that resulted in us having some awesome characters, both teachers and students. There's this one moment I would never forget.

Unlike in K.L. we had all our classes in one classroom unless we had to go to the lab and stuff. The teachers were the ones who used to go from class to class. Then one day our teacher was late for class so we started making a noise when the high school disciplinary head Mr. Rai came into our class. He's a great man and very commanding.
The moment he entered our class:

Mr. Rai: Good afternoon boys (boys and girls were in separate classes)
Students: (In a very boring droning song which was our way of irritating our teachers) Good morning sir.
Mr. Rai: It's afternoon boys. Let's try this again. Good morning boys
Students: Good afternoon sir.
Mr. Rai: Good. Who knows about The Ant and Toothpick?
Students: Huh?
Mr. Rai: (becomes very passionate) One day, ant carried toothpick. The next day, ant died because toothpick was too heavy. Whats the moral of the story?
One student: Don't take on more than you can do?
Another student: Look before you leap?
Mr. Rai: You idiots ... the moral of the story is ... DON'T CARRY TOOTHPICK!!
Students: WTF???....
