Evolution of Percy Penis

When a child is born & turns out to be a he
They are taught that Percy is there just to pee
Point Percy to the porcelain yeah that's the way son
You learnt really fast how its done
Through the years things start to change
He realizes Percy has a much wider range
As he gets older & testosterone starts to rise
He knows Percy must be given some exercise
Over time he goes at it hammer & tong
Age creeps up & before too long
Percy no longer salutes to the sky
Frustrations enough to make a grown man cry
Its back once again to splashing the shoes
He lives on memories & sings "Percy porcelain blues"
