I'LL PAY YOU BACK - A swear you make when you're too broke to pay but too proud

A swear you make when you're too broke to pay but too proud to admit it.

I'll pay you back... when I'm not broke and I'm not too proud to ask for help.

I'll pay you back... after I find a million dollars in my sock.

I'll pay you back... when I'm not broke and my pride goes on vacation.
