Answer 5

My favorite a poem by comedian Demetri Martin.  The whole thing is a palindrome!!

Dammit I’m Mad -  by Demetri Martin

“Dammit I’m mad.

Evil is a deed as I live.

God, am I reviled? I rise, my bed on a sun, I melt.

To be not one man emanating is sad. I p**s.

Alas, it is so late. Who stops to help?

Man, it is hot. I’m in it. I tell.

I am not a devil. I level “Mad Dog”.

Ah, say burning is, as a deified gulp,

In my halo of a mired rum tin.

I erase many men. Oh, to be man, a sin.

Is evil in a clam? In a trap?

No. It is open. On it I was stuck.

Rats peed on hope. Elsewhere dips a web.

Be still if I fill its ebb.

Ew, a spider… eh?

We sleep. Oh no!

Deep, stark cuts saw it in one position.

Part animal, can I live? Sin is a name.

Both, one… my names are in it.

Murder? I’m a fool.

A hymn I plug, deified as a sign in ruby ash.

A Goddam level I lived at.

On mail let it in. I’m it.

Oh, sit in ample hot spots. Oh wet!

A loss it is alas (sip). I’d assign it a name.N

ame not one bottle minus an ode by me:

“Sir, I deliver. I’m a dog”

Evil is a deed as I live.

Dammit I’m mad.
