Doggone Stunning Specimen

Okay friends now let's just see
Do I have weaknesses of my own?
Nope, after careful investigation
I find I'm just perfect to the bone

A doggone stunning specimen am I
Of a homo sapien supreme
With bulging muscles everywhere
My tummy is tight and lean

So muscle bound, can't even bend
To tie my oversized shoes
Haven't seen some parts of my body
Since ninety-sixty-two

What's my secret you may ask
To my Greek Adonis form?
I chew on nuts and alfalfa grass
Celery and cobs of corn

Not your cup of tea you say?
So keep up your over stuffed ways
Like the famous Goodyear blimp
You'll go drifting off in the haze!

Tongue in cheek???
