Rock Group:

I have a squared head
My face blushing red,
I never keep to myself
Unless I'm in the bed.

Im so often duplicated
But I'm one of a kind,
A chip off the ole block
Just as I'm designed.

I'm toughter than wood
Can whip straw's lil butt,
For them both together
Can't make my cut.

Water is no competion
My sands are held tight,
I'm stronger than glass
I hold off the daylight.

I have a six sided diagram
And awhole lot of friends,
When I'm fully connected
To whatever my arms mend.

I'm much smaller in statue
Than a single cender block,
But I'm a fairytale's giant
To a handful of little rocks.

I'm durable as a building
But crumble as cookies do.
Can be fixed or repaired
But not with super glue.

Yeah you know what is said
But it's only Pink Floyd's call,
For I am nothing but another
Just another brick in the wall.
