"Just Bring Yourself"

Got invited to a Halloween party last weekend.  Fondue? More like Fon-don't.

Made a phone call to ask what we should bring. 

"Oh, just bring yourself!"

Uh....what? 

Of course I'm bringing myself you idiot. You invited me.  Why wouldn't I bring myself. Why don't you just say, "We've got everything covered. It's our party and we're not cheap-A peeps who throw a party but make everyone bring stuff."

If I invite you to lunch, I pay for lunch. If you throw a party, you buy everything. 

Please stop saying, "Just bring yourself!"
