The funniest thing I've ever heard at work

Following is a conversation I had at work last night at 4:30 AM:

(ring, ring. Call bell. Room 132. So I walk to the room.)
Can I help you, Maria?
--Yes, I need a chinese name.
A Chinese name? What?
--I've never had a chinese name.
(At this point I explode into giggles.)
Maria, it's 4:30 AM. How about we call you Lily?
--Oh, that's nice dear.
Goodnight, Martha.
Goodnight!

I'm waiting for her to ask me what her Thai name is.
