Arrch says:
Ebil Ebeninb, Miss Isilme!
Isilme says:
Ebil Ebeninb!
The phrase "Ebil Ebeninb" has a long and illustrious history.
I think it started shortly after the end of the third age, when the evil elf Funevil started making an appearance. Funevil corrupted the common saying of "Good Morrow" or "Good Afternoon", or "Good Evening" to one more sinister, where the word "good" was replaced by that of "evil".
So instead of "Good Afternoon", one would say "Evil Afternoon". Instead of "Good Evening", one would say "Evil Evening". But a few months ago, the gods of literacy and spelling went on a short vacation, leading to a proliferation of typographical errors and typmos.
And hence, one night, the Arrch said to lady Isilme, "Ebil Ebeninb", in a strange mixture of uncoordination and touch typing.
So the phrase "Ebil Ebeninb" was born, and it stayed, because it seemed much funnier and tormented Funevil to no end. And ever since then, people all around have been saying "Ebil Ebeninb", to ward off the mischief caused by Funevil. And also because it confused others who did not understand.
