The Navy makes it a debit.
Every month has 30 days
(Now keep that well in mind)
Unless you leave at 2400
And say August 29).
That really makes it 30
(Somewhere they always add 1)
So, tho' you only get pay for 30 days
You get checked for 31.
Now follow the simple logic
You're ready to ask for your sum
Sign for 250 grand---
Portsmouth, here you come!
