[Chorus]
Trust me to open my mouth
Now everybody knows
Trust me, now I've let you down
I'm a big mouth, I suppose

[Verse 1]
This was our secret, our meetings were so discreet
I promised to keep it from the ears out on the street
This was our secret, we were having an affair
I couldn't keep it, now the secret's everywhere

[Chorus]
Trust me to open my mouth
Now everybody knows
Trust me, now I've let you down
I'm a big mouth, I suppose

[Verse 2]
One cup runneth over loosening a jaw
Trust me to open my mouth it's not a secret anymore
We had a secret, what a terrible thing to do
I couldn't keep it, I was so in love
So in love with you

[Chorus]
Trust me to open my mouth
Now everybody knows
Trust me, now I've let you down
I'm a big mouth, I suppose
[Bridge]
I need a gobstopper to keep my trap shut
Should've kept my nose clean
Why's it me that gets the bad luck?

[Guitar Solo]

[Chorus]
Trust me to open my mouth
Now everybody knows
Trust me, now I've let you down
I'm a big mouth, I suppose
Trust me to open my mouth
Now everybody knows
Trust me, now I've let you down
I'm a big mouth, I suppose

[Outro]
Trust me to open my mouth
You've got a big mouth
Trust me to open my mouth
Keep it shut
Trust me to open my mouth
Trust me to open my mouth
Zip it up
Trust me to open my mouth
Loose lips sink ships
Trust me to open my mouth
Trust me to open my mouth
