Oh, good idea! *Duh* Why hadn't anyone else thought of that?

what does duh mean?
Homer Simpson uses it frequently - go figure!
Duh != D'oh!
Duh: A sort of sarcastic remark when something is obvious. "1+1=2, not 8, duh.
D'oh: A remark usually used to express (comical) disdain. "I stubbed my toe on the door frame again! D'oh!"
...Duh...
