I Can Has Hot Dog is one of my favorite dog sites. It's just so silly! All these funny pictures of dogs (they now have cats and celebrities, too) with ridiculous captions. The captions are not standard English-friendly (which sometimes makes it difficult to read), but they are so funny that it works. Kind of like Chick-Fil-A cow writing (chikin).
Anyway, I tried my hand at a couple. Whaddya think?
