Have you ever: Price In the Frame

Hi Off Topic

LongStoryShort

Today my parents offered me 8.000 JD for when i'm going to study abroad. I decided to make them a painting as a sign of gratitude. I also decided to write the price inside the frame. As a reference to my gratitude.
This made me think.

The Question is:

How often does this happen?

What kind of artists have done it? (do i know any?)

Have you guys ever done it?

Is it considered a dick move?

Hoping for answers
