User blog comment:Dr. Nygma 1048/Ferb's real name/@comment-4068793-20110813112028

I found good news. His name is based off of a mutual friend of Dan Povenmire and Jeff Marsh's named Frank. His wife said that she disliked his name and gave him the nickname Ferb. Just because the guy he is based off of is named Frank, doesn't mean that's what Ferb's name is.
