My Favourite Poem!

Whosever room this is should be ashamed!
His underwear is hanging on the lamp.
His raincoat is there in the overstuffed chair,
And the chair is becoming quite mucky and damp.
His workbook is wedged in the window,
His sweater's been thrown on the floor.
His scarf and one ski are beneath the TV,
And his pants have been carelessly hung on the door.
His books are all jammed in the closet,
His vest has been left in the hall.
A lizard named Ed is asleep in his bed,
And his smelly old sock has been stuck to the wall.
Whosever room this is should be ashamed!
Donald or Robert or Willie or--
Huh? You say it's mine? Oh, dear,
I knew it looked familiar!

This is my favourite poem from http://famouspoetsandpoems.com/
This poem is entitled "Messy Room" by Shel Silverstein.
He names the lizard that lies on the bed "Ed", making it out to be a human being. He also uses a lot of adjectives to describe more about the messy state of the room. He also uses a quite adequate link of rhyming words at the end of each line, thus making the poem easier to read. He also uses a lot of humour in his poem.
The last four lines are a very good example of his humour. He says that whoever is the room's owner should be ashamed. However, he realises that the room is his and looks familiar. In the end, he has himself to be ashamed for because of his messy room! His criticism had backfired!
