~ Gönn dir was gutes ~
I think you get the idea of the verse from the comical scene on this novelty, glass stein without lid, ca. post WW II.
Gönn dir was gutes
auch wenn du in Not bist
was nützt dir was Leben,
wenn du erst Tot bist.
Do not begrudge yourself
when you are in need
(of) what's of use to you in life,
if you soon will be dead.
