I Heart Lily

Last night I saw I Heart Huckabees which was hysterical even if it did make fun of poetry. I want to be an existential detective. Lily Tomlin's performance and facial expressions were priceless. She should do more movies.

Does anyone have any existential poetry recommendations? Aside from that Donald Rumsfeld book. A lot of poets probably fall under this catgory at one time or another. I don't think I've given a book or poem a close existential reading since my undergrad days.
