I occassionally steal the safe for work images from kippage. There I said it. I've been reluctant to pimp the site before, because well.... it has photos of boobs on it alot. But some times it also has starwars and kitten related images, which I also like. To be honest though, when jadz0r finds an image which includes boobs, starwars AND kittens all at once it really cracks me up.
I predict that I'll also be stealing some of the safe for work images from image88. I also predict many classic boobs, formular 1, kitten and geek reference cross over images which will surely be amazingly entertaining too.
