Isn't Moe a Jewish name? Moe of the Three Stooges real name was Moe Horowitz. And there was Moe Green who got shot in the eye in the Godfather
I was going to suggest you call him by his last name but that might not be a workable solution either.
Remember when that Asian Airlines plane crashed and somebody called a TV station with the names of the pilots? They were something like: We Too Lo Bing Bang Ow Ho Lee Fook
Back in the 80's I lived in Mobile for a couple of years. I'm not real good at remembering names so whenever I would see a man I had met before I would just call him Bubba. At least half the time I was right. One time when I hadn't been there long I got lost on some road trying to take a shortcut to I-10. I was in some hilly backwoods looking area and I saw this guy working on a truck that looked like it was a 57 or 58 really old truck. He had the hood up and when I stopped he got out from under the hood. He was a big rawboned looking dude wearing a Red Man tobacco cap. I said "Hey, Bubba! Which way to the Interstate?" He looked at me and said: "I from Germany. I speak no English."
