1. "You think I have a family? Really? I was born in a war that had little to know servicers."

2. "you think the Cold is bad. try having Small Pokes, Yellow Fever and Black Death all at the same time."

3. "the us troops were nice to me, even though I was German and Russian, but we both look the Germans out together. they didn't see that coming."
