I would use the "credited as" feature in this case. These are indeed fake credits so I would look at other Simpsons episodes to find who is who. Then, using the credited as feature, I would input their real names but add "credited as" with the fake name.

Maybe copy-paste this for John Frink3 and see if it works in DVDprofiler?

I don't know the ASCII codes of all these characters by heart, but if this happens again, you can always go in MS Word, click Insert> symbol, double-click the symbol you want and then copy-paste it into DVDP.

OK, I was doing episode 5 credits and came across 3 people who are usually credited as Co-Producers. I think these are the following credits


Larry Doyle = Larry Doyle!!!
Tom Martin = Tomb Martin
Carolyn Omine = Carolyn Omen


But I can't figure out whom to link to for the final two credits.

John Frink3
Don "Excruciating" Payne

Any help?

Yes, the credits for the Simpsons Horror specials are always fake credits, but based on real credits. They just take the real credits and alter them to make 'scary' versions of the cast & crew.

This isn't really specified in the rules but since these are obviously the same people, I would go with the credited as feature if you could identify them all.

Thanks for the work you put into this. I'm sure everyone will appreciate it.

Luckily these producers were later credited later on in the season so I was able to link them. That's why it was difficult to figure out who they were "crediting" with the made up names.

I'm about half way done now, should be able to get it done by tomorrow morning.
