 If you liked Heppoko Jikken Animation Excel♥Saga |  ...then you might like Gintama° |
Excel Saga is best described as Gintama before Gintama. Without Excel Saga, there wouldn't really be a Gintama. Both are goofy parody type anime- Gintama parodies more specific anime whilst Excel Saga likes to parody genres in general. Both have a story, however it only begins to move at the end of the series. If you like Gintama and can't wait until it's next season, consider watching Excel Saga.
