Mrs. O'Donovan: Mercury is determined to be dangerous in developed countries, but luckily not in developing countries, so we can still play with it outside of school... or I can have it in school if I don't tell anyone.
O'Donovan: I ask class, "Where are all the students?" and they tell me, "It's 4.20. what do you expect?" So I ask, "What is 4.20?" and they say, "No, no we can't tell you that, you'll look badly on other students." So I go to the internet, I see what is 4.20 and I look badly on MATTAN who was not in class.
