Tenth allied soldier

A patrol of allied soldiers were in a ruined city during World War Two. They are bragging and joshing about how many kills they have so far to keep up courage on their route through the rubbled buildings. Sergeant Joe thumps his chest and proclaims. "I got me 4 germans bagged so far. How about you John?" Before Pfc John can reply, a lone german soldier runs out of a trashed hotel. In the process of throwing down his rifle after seeing the larger allied soldier group, he shouts "NEIN!" Pfc John takes aim at the enemy and shoots him. "Well, he won't get himself a tenth allied soldier." Joe all year long!
