A [blarney stone]
Blarney Stone is when you kiss a rock and then talk so much it’s like you’ve got a mouth full of silver coins and a tongue that can convince a dead man to come back just to listen to you.
My friend kissed the Blarney Stone and now he talks so much he’s like a broken radio that won’t shut up.
My cousin kissed the Blarney Stone and now he can convince a chicken to lay an egg at midnight.
My brother kissed the Blarney Stone and now he’s trying to convince my mom that he’s a wizard.
