Ten

In the first panel, Calvin sits at his desk doing homework. Appearing above his head, the text of what he's writing reads For my science-fair project, I propose we dose every teacher at school with a double-stacked ecstasy pill.

Hobbes watches him write in the second panel If my theory is correct, all of the teachers will begin to feel really happy and awesome and not care about the trivial bullshit that drags us down in our daily lives.

In the third, Hobbes is compelled to comment I don't think your teacher is going to be receptive to this experiment.

In the next panel, Calvin states Receptive or not, I can't get a refund. My guy accidentally OD'd over the weekend.

Hobbes is shocked Gosh! On ecstasy?

No, no. Calvin replies. Heroin, I think - I'm pretty sure at least. He goes back to writing.
