ケロロ軍曹☆ or Sgt. Frog

If you like cartoons or Japanese animation, consider Sgt. Frog. It's a story about a sentient frog being and his friends from outer space. They try to take over the world, and have hilarious adventures. There's a narrator, as well as random subtitles saying funny stuff. It's got a lot of energy, and keeps me entertained through out an entire episode!
