2) They are ornamental. Although as with all art, beauty is in the eye of the beholder. And evolutionists routinely deny that anything is ornamental. You are such a brazen liar. Ever hear of "sexual selection?" Of course you have, but you oh-so-conveniently forget it to make a dishonest point. Everything from peacock tails to elk antler to blonde hair is "ornamental" but also serves to attract mates.
As for external ornamentation, one need look no further than crows and certain crustaceans as examples of critters collecting do-dads or ornamenting themselves to attract mates.
I suppose you've never heard or used the pick-up line, "want to come up and see my etchings?" Same deal.

OK perhaps I over generalized. The reason I made that comment was due to the web search I made on male nipples to see if I overlooked anything. Most of the evolutionist explanations that explained that male nipples were becaused we evolved from lower animals that had them, started off with the statement that "They are not ornamental". (Search WebMD.com for male nipples).
How they can make such a blanket statement is beyond me.
Nevertheless, I stand corrected, and apparently evolutionists only reject male nipples as ornamental. Ornamental items can indeed be seen in much evolutionist work.
Although I am curious why evolutionists think ornamentation evolved as an aspect of sexual selection. It seems like brute strength and stamina would be preferred.
In other words.. If we were evolutionary products,
wouldn't we deem this... 
attractive over this?.... 
Post 231 is where you get to quote Jim Croce's Rolly Derby Queen lyrics. LOL
Roller Derby Queen - Jim Croce
Gonna tell you a story that you won't believe
But I fell in love last Friday evenin'
With a girl I saw on a bar room T.V. screen
Well I was just gettin' ready to get my hat
When she caught my eye and I put it back
And I ordered myself a couple o' more shots and beers
Chorus:
The night (you know) that I fell in love with a Roller Derby Queen
(Round and round, oh round and round)
The meanest hunk o' woman
That anybody ever seen
Down in the arena
She were five foot six and two fifteen
A bleached-blonde mama
With a streak of mean
She knew how to knuckle
And she knew how to scuffle and fight
And the roller derby program said
That she were built like a 'fridgerator with a head
Her fans call her "Tuffy"
But all her buddies called her "Spike"
(Repeat Chorus)
Bridge:
Round and round, go round and round (3 times)
Well I could not help it
But to fall in love
With this heavy-duty woman
I been speakin' of
Things looked kind of bad
Until the day she skated into my life
Well she might be nasty
She might be fat
But I never met a person
Who would tell her that
She's my big blonde bomber
My heavy handed Hackensack mama
(Repeat Chorus)
(Repeat Bridge)
