"I welcome him like I welcome cold sores. He's from England, he's angry and he's got Mad Power Disease"

This quote by Paula Abdul is a funny way of expressing her sensations about someone she is not particularly keen on. She is comparing the person to a cold sore, which is an unwanted and unpleasant event. The individual is from England, which might be a reference to the stereotype of English people being bad-tempered and unfriendly. The phrase "Mad Power Disease" could be a metaphor for the individual's conceit and sense of superiority. It could also be a referral to the idea that power can corrupt people and make them behave in a manner that is not socially appropriate. In general, the quote is a funny method of expressing Paula Abdul's dislike for the individual in concern.
