S4E21 Teeth for Two

After a misunderstanding, Jorgen ends up staying with Cosmo and Wanda when the Tooth Fairy accuses him of trying to steal her job. In reality, he was just trying to extract Timmy's teeth, which he believed were the 'dental equivalent of the Hope Diamond,' intending to use them as a unique engagement ring for her.
