[Strangler Lewis]

I lunch Lucy . . . and she lunches me.

Did Everybody Lunches Raymond have a theme song?

And I guess we could move beyond songs into literature:

E.g., Women in Lunch; Sons and Lunchers by D.H. Lawrence

Of course, there's Lord Alfred Douglas's poem "Two Lunches," which spoke of the lunch that dare not speak its name.

And William Burroughs's "Naked Love"
