my mistress' eyes are nothing like the sun

this poem has a humerous side to it because the speaker is making fun of someone. he is picking out aspects that we are used to hearing boasted about and instead is downgrading them. he does this in a nonchalant way; not a mean, point-your-finger obvious kind of way. the author uses similies to enhance his picece by comparing red coral to the mistress' lips. he also uses a metaphore where he compares her hair to black wires. this poem makes me think that the speaker must have thought very hard over how much he dislikes his mistress' appearence to be able to come up with words and ideas such as these.
