I love Betty Brown's mother 
I hope it's not against the law 
I just love Betty Brown's mother 
Though she is my mother-in-law 

No I've never been unfaithful 
I've been a one woman man 
Now I don't want to sound ungrateful 
but I'd like to extend my family plan 

I love Betty Brown's mother 
I hope it's not against the law 
I just love Betty Brown's mother 
Though she is my mother-in-law 

I know this is a risky business 
and I dare not upset the wife 
The older woman it pleases 
To the younger's a danger in life 

I love Betty Brown's mother 
I hope it's not against the law 
I just love Betty Brown's mother 
Though she is my mother-in-law 

'When Betty Brown hear this sound 
she's gonna think I'm a clown 
and I don't want fo' she to put me down 
But I had to bring myself around to tell her'
