The chicken was an Easter egg of sorts. You know how people say "chicken stamps" when talking about German stuff? That's become one of my biggest pet peeves. The only thing worse is "waffenmarks" (cousins of waffendaves) and "swazis."
So I imagined the 03a4 killing the "chicken stamp" while the PU got hammered on vodka and the zf41 ****ed and moaned about its atrocious eye relief and field of view. Leave it to America to have to mop up the world's messes.
