I find this stuff? Man, that's a question of the Universe.
But regardless, it comes to you via the fine folks at OfficePirates.com. Some of the best stuff I've seen in a while. So simple, yet, so effective. Enjoy.
The entire site has great stuff. And the best thing? It's ALL very safe for work. Unless you work in a place that frowns upon cackling and giggling...then tough shit Paddy...
