It's called "Nobody Believes Me" sure it's only a few lines, but good lines! Read it!
Nobody believes me
If only they could see me
The way I am when I'm in need of help
I won't be there to help them
And nothing's gonna happen
I need someone to give me help
When nobody believes me...
so sad. I wish there was someone on the show who REALLY believed Dib. According to the ep "Zim Eats Waffles" even his fellow SEB members think he's crazy! :(
