For this easter egg, you first need
to open the mIRC about screen. When you are
there type in the word "arnie" (without the quotes). If you are successful,
you will see a picture of Arnie in place of Khaled's picture. From
what I know, when Khaled was asked about this, he said it was because Arnie
helped him make mIRC. You may change the picture back by typing "arnie"
