There were these three prisoners in a German POW camp, and they were Australian, American, and Irish. The commandant was a real mean prick and he was going to shoot his three captives unless their combined dick length was in excess of 20 inches.

So the three POWs have their cocks measured and it turned out their combined dick length was 20 inches exactly, so they were spared.

Later on the three were talking, and the Australian said "Well if it wasn't for my 10 inch dick we'd all be dead."

The American says "Na, if it wasn't for my 8 inch dick then we'd all be dead."

Then the Irishman says "If I didn't have a hard on, we'd all be dead."
