Lukas

Legend.

I wish I could be like Lukas.

Darum geht's nicht

It's a german phrase which was invented by Dr. Linus. He always uses it when he doesn't know what to do. It's like a home for him, where he's safe when he's in trouble. It's his everything.

Someone: "Which grade do you have in maths?"
Linus : "Darum geht's nicht."
