Dan Castellaneta, the Voice of Homer
About Homer's infamous "D'oh!"
"It was written into the script as a
'frustrated grunt' and I thought of that
old Laurel and Hardy character who had a
grunt like 'D'owww.' I did it and
Matt Groening (Simpsons creator) said
'Great, but shorten it' and this is what
I came up with. Matt liked it and
I kept it, but no one knew it would
become a catch phrase."
