Germanic Powder Horn Phrase

[Chris Treichel]

I was talking about some Jaeger Rifles this past weekend.  Ran accross a really beat up Percussion converted one on Friday in a Kensington Maryland Gun/Railroad hobby shop. Anyway latter was talking about making a new horn for a more Germanic Gun and the fellow I was talking to pops out a neat little bit he said he recalled reading on a horn.  Anyone ever hear this one and know where it came from?

Es taugt dir keine Kunst
Wenn Dier ein Engel in die Pfanne brunst

No art/refinement will do you good
if an Angel *#)*^! in your pan

[Ahtuwisae]

Have also seen it as

Alle Anstrengungen sind vergeblich, wenn ein Engel pisst in der Steinschloss-Muskete Ihrer
All efforts are in vain if an angel *#)*^! in the flintlock of your musket


Not sure of the origon though.
