A [blarney stone]
It’s a rock sticking out of a castle in Ireland, and tourists go and kiss it like it’s the last thing they’ll ever do.
My aunt kissed the Blarney Stone and then told me she could talk her way out of a prison sentence.
My cousin’s friend kissed the stone and now he thinks he can convince a chicken to lay an egg at midnight.
My uncle kissed the Blarney Stone and then tried to flirt with a statue. It was weird.
