This happened many years ago when I was in high school (I went to a girl's school). We were taking biology class, and learning about anatomy. During one of our laboratory sessions, we were required to dissect a fish. All of us did it and showed them to the teacher. She proceeded to grade us, and returned to the board to teach us about frogs.
One of the girls yelled "We should dissect frogs!!!". The teacher said, "Look, we have frog kits which you will use to learn about this. You don't need a real frog". Some of the more adventurous girls were grumbling loudly at the back of the class.
And suddenly, a tiny frog hopped into the class.
We were on the THIRD floor! I don't know what the frog was doing there, but there it was hopping in through the front door as if on cue. There was total silence in the class for a few minutes as we all (agape) watched the frog hop in. Even the teacher had her jaw on the floor. None of us could believe this was real or that we weren't on Candid Camera.
The frog hopped and hopped until it reached one of the legs of the teacher's table. And sat there.
And then MAYHEM
. The girls started running like monkeys after the poor frog (who was only the size of our palm). The frog darted left and right while the teacher banged the table fruitlessly in a failed attempt to return order to the classroom. Girls were shrieking and jumping on tables and chairs (afraid of the frog), girls were chasing the frog, girls were cheering the ones chasing the frog and girls were making fun of the other girls on the tables and chairs. It was insane.
Finally after 10 minutes, they caught the frog.
Order was restored.
Then the girls who caught it asked the teacher for permission to dissect the little frog. The teacher (trying to look stern) told us that the frog was too tiny to be of any use to our knowledge. She took the frog away from the girl and told us to concentrate on our frog kits.
No one could work that day.
We named the frog "Hoppetty". Hoppetty was released into the school field that very afternoon, to the relief of some of the girls.
Some girls continued to hunt for him during Physical Education classes. They were unhappy that they never got to dissect Hoppetty that fateful day.
Conclusion: Schoolgirls are nasty. Save the frogs.
