There

Their they are, there the people that spread mistakes across this page.
I should've known better to trust them.
Their known for how well they can confuse you.
There allowed to do whatever they want.
We're in for it now that there on the loose, I feel like a strangled goose.
They're minds are full of evil, wanting grammar mistakes;
They climb into your mind and their hard to get out.
My teacher warned me and tried to teach me there after us but he sounded mad.
But here they are now and they're stupid teeth are biting into me, telling me to put they wrong one down.
Those darn words. There's their, there, and they're but if you put them in the wrong sentence, you are "GRAMMATICALLY STUPID!"
