I read in the paper a few weeks ago that the word "d'oh" now appears in the Oxford Dictionnary. As a die-hard Simpsons fan, I am elated to say the least.
On a completely un-related note, I would like to say that this was a brilliant military strategy. If this trend continues, soon enemy nations will be rendered weak due to the singular lack of communication resulting from the adoption of our words such as "d'oh!"
In the event of a war, their government officials will have the follwing dialogue:
"D'oh!"
"Bombs away"
"Cowabunga dude!"
"Jawsome, we're Street Sharks"
"You maniacs, you blew it up. Damn you. Damn you all the hell."
