I'm Your Mailman

I feel happy, I feel gay
Cause I come twice a day.
I'm your mailman.

I don't mess with keys on locks,
I just stick it in your box.
I'm your mailman.

I can come in any kind of weather,
For you see my bag is made of leather.
I'm your mailman.

Oh! Pat you knockers, ring your chimes,
For you see mine is fine.
I'm your mailman,
With the longest route in town.
