Terrible Nat King Cole knock-off that was supposed to be funny...

I'm forgettable, both day and night. 
When you guess my name, you're never right.  
With her look of love concealing me, 
it's no wonder you're not feeling me. 
Just like before,
You're closing the door.

I'm forgettable in every way, 
and forevermore that's how I'll stay.
Oh, my darling, you're not credible,
so I'll eat all that is edible,
'Til I find that you're forgettable, too.
