i've toked before and duriong school, and i can't concentrate for shit. the teacher says "duty" and i crack up and then i laugh more because of the fact that i'm laughing at the word duty and then i laugh even harder because my laugh sounds funny. then the person next to me laughs with me, making me laugh even harder, and at this point i can't breathe and the teacher is trying to ask me what's so damn funny and i can't talk because i'm laughing too damn hard. so i get sent to the office and sit in the vp's office still laughing because he said "duty" too.
