Columbine's Reading List

Alright, listen up, you big dummy. The joke is playing on the word 'magazines'. Most people think of reading material, like you probably pretend to do. But in a dark context like Columbine, 'magazines' also means the things that hold bullets for a gun. It's a twisted pun about a real, awful tragedy. You probably didn't even realize Columbine was a school, did ya?
