It sounds impossible, but a squirrel set off a fire alarm at an elementary school in Ellenton, Florida. Did he forget to study for a test?

Security camera footage shows the furry prankster scaling a wall, then hanging off the alarm's lever, setting it off in the process.

Officials initially fined the school for the incident, but decided against a penalty when video of the squirrel doing the deed came to light.

Watch footage of the ne'er-do-well squirrel below.
