Here it is... the biggest Simpsons list in the world! The definitive "D'oh!" list!!! I don't know if this has been done before, but I have never seen it on any sites that I have ever been to, nor has it ever come up on newsgroups. You can also find this list at my site, The Simpsons Club, at http://simpsonsclub.topcities.com/lists/doh.htm .
Seasons 1 to 6 are in this post, and 7 to 12 in another. Note that Season 12 is not complete. I have included times when other characters have said 'D'oh' as well, so unless otherwise stated, the character saying "D'oh!" is Homer. Enjoy!
