He made a huge post this morning of The Simpsons, some South Park and the Oblongs. He doesn't care if you credit him or not, however he likes comments if you're taking.
The first Simpson link is here.
You can use the navigation arrows at the top of the page to go froward to see the rest of the Simpson icons, then the South Park, then the oblongs.
As I said before, credit is not necessary, however please leave him a comment acknowledging him and thanking him - he loves that!
