Prankster Obvious Plant Leaves Free Biology Report Outside High School

Prankster Obvious Plant is well known for leaving totally fake signs, leaflets and other literature lying around and bringing laughter to locals across his home state of California.

This time, the viral mastermind has written a free biology report and left it outside a school.

It's titled 'Wolves: Why Are They So Badass?' and it gets full marks from us.

We envy the lucky kid who picks that up.
