If you want to, you can choose to NOT write a verse and be a judge instead. Maximum there will be 5 judges. Judging will happen in one week. Just comment under one of my posts with your results if you are a judge, and I'll find the average scores and choose the winner from there.
As a demonstration, Here's my attempt. Its terrible, and you can do better than me, but I'm bored:
Don't got a tongue as long as a frog
And I also don't own a dog
I also don't drink grogs
But I got a massive garage
And that's it!
