Since I have no prior knowledge of this specific phrase, it's hard to say for sure where it came from. It could potentially be a line from a local play, or an inside joke within a particular group of people. Maybe Ferb was known for doing quirky things, and this was a comment about one of his attempts at something, but without more context, it's all speculation.
There's not enough information to accurately pinpoint the origin. It might have been created spontaneously in a conversation, or it could be from a relatively unknown piece of media. It could be that Ferb is a unique name within a small community or group, and this was a comment related to something Ferb was doing.
I don't really know the origin. It could be a made - up phrase by someone for a specific purpose.
