Messy room discussion

Messy Room by Shel Silverstein

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!

Well, this is an awesome poem as it has a touch of humor in it. It used personification as the poem stated the "A lizard named Ed is asleep in his bed".
The lizard carried human traits.
