It's also very close the the name of an anime character "Anpan Man".
I read about this character in Manga Jin's Learn Japanese through comics!
I had worked in the electronics field for a few years, during which time, Scott Adams created the Dilbert character & comic. I really hate making up stuff, because I fear it will suck and people will laugh at me. So, as among the supporting characters were catbert, ratbert, & dogbert, I figured jeffbert would not merit too much criticism.
When I was a kid, we had really a tough time naming our GI Joes. This was way before they had names or personalities. Since then, I took several hours trying to come up with a email name that would not stink!
I came up with mine in late 1999 at a private LAN game where we were trying out the Quake 3 beta. It was one of the first multiplayer games I played where you had to actually choose a name, so I chose DrFrag (a frag is when you kill someone in the game).
I started my love of PCs with Wolfenstein 3D, Doom, and several other 3D immersion maze games. Since then, they have become much more complex, and the idea of playing with only one hand, as I do, was too frustrating.
I remember a Wolfenstein game editor that I downloaded. It was fun! I could build my own mazes, put the bad guys anywhere I wanted, in any number. But the
Bosses were weird. Unlike all the others, they would not move at all, unless you put them behind doors, and opened them!

You could take the chain gun and spay them until they died (took about 100 rounds), and they would just stand there, unless you opened the door! I tink I killed them with the knife at least once, it took about 500 stabs, though. I had no interest finding out how many punches it would take!
Itried to use a similar Door game editor, but could not create games from scratch, the best I could do was edit existing mazes, usually puting the Cyber Demon in more than one place. :wahah: :wahah:
