Spongebob = Zach Braff on Scrubs?

I’d never seen an episode of Spongebob Squarepants until today, when my son was watching it. When I heard Spongbob’s voice, I immediately thought of Zack Braff’s character on Scrubs, J.D. Dorian.

The similarities are very uncanny. Has anyone else ever noticed this? I found it unsettling, almost like Zach based his Scrubs character on Spongebob (or the other way around?).
