From "Overheard in New York."

Girl: "What's the plural of 'Jesus'? Jesuses? Jesi?"

Friend: "Why would you ever need to pluralize 'Jesus'? There's only one!"

Girl: "Well, like, if you were at a Halloween party or something and you had to tell your friend 'There were, like, eight Jesi at the party last night."

Friend: "Just stop talking."
