How can I blow off steam tonight? (It's been another rotten day)

At the end of the day, we had several students going off, then a girl in my classroom decided to punch a hole in the window and refused to have her hand looked at for 15 minutes. Then, just as we got the kids on the last bus to go home, another kid started acting up and it took 20 minutes to get him off the bus. Now, I’m swamped with paperwork for the rest of the afternoon, when I really just need to breathe…Not to mention my car is acting up and I don’t feel like taking it in to have it looked at after the day I’ve had…

So…serious answers or something to cheer me up…I don’t care which, but give me a way to forget my day…
