I'm 20, but I love this show because it's funny. I wish I could see more episodes than I have.
The show features around Stitch and Mo, two school students who have an advantage to learning history: Some voice-over guy sends them back in time to whatever period they need to learn about. From there, plenty of wacky hijinks are involved. But, it is also educational. Between the gags some real history is learned. For example, in the viking time period, they learn that the viking horns are only used for ceremonial purposes, something that I learned in high school. They then use this knowledge to upstage their snooty classmate in a school presentation.
I thoroughly enjoy watching this show, and if you ever notice it in the TV guide, check it out.
