Mother In Law
Huey Lewis & The News Lyrics

The worst person I know, mother-in-law, mother-in-law
Huey Lewis is referring to his mother-in-law as the worst person he knows, which is an indication of how he feels about his mother-in-law. He repeats this statement twice to put emphasis on how terrible he thinks she is.

She worries me so, mother-in-law,mother-in-law
Huey Lewis is worried about his mother-in-law so much that he repeats the line twice. It could be that her behavior towards him is causing him stress and anxiety.

If she leaves us alone, we would have a happy home
Huey's mother-in-law could be living with him and his wife, which is causing trouble in their marriage. The line suggests that the couple may be happier if the mother-in-law left them alone.

Sent down from below Mother-in-law, mother-in-law, mother-in-law, mother-in-law
This line could suggest that Huey's mother-in-law is from hell because of the trouble she is causing Huey and his wife. The repetition of the term 'mother-in-law' is for emphasis on his frustration and how annoying she is.

Sin should be her name, mother-in-law, mother-in-law To me, they're about the same, mother-in-law, mother-in-law
Huey Lewis feels that his mother-in-law is such a bad person that 'sin' should be her name. He also thinks that she is the same as her name, which suggests that her nature is sinful and immoral.

Every time I open my mouth, she steps in, tries to put me out How could she stoop so low? Mother-in-law, mother-in-law, mother-in-law, mother-in-law
Huey Lewis's mother-in-law is always interrupting him when he speaks or trying to silence him. He is surprised by her behavior and can't understand why she is being so rude, and insensitive causing him to repeat his frustration with the expression 'mother-in-law' multiple times.

I come home with my pay, mother-in-law, mother-in-law She asks me what I make, mother-in-law, mother-in-law
It could be that Huey's mother-in-law is overly interested in his finances, He could be suggesting that she cares more about his money than him or his relationship with her daughter. It could further imply that she is trying to control his life as well.

She thinks her advice is a contribution But if she will leave that will be a solution And don't come back no more Mother-in-law, mother-in-law, mother-in-law, mother-in-law
Huey Lewis's mother-in-law tries to give him advice, which he perceives as unhelpful, annoying and condescending. He thinks that the only solution to the problems is for her to leave and stop causing problems. Hence the repetition of 'mother-in-law' shows his frustration trying to tell her to leave.
