No Export for You: This has aired in other countries (dubbed), but not in the US. Some say that the creator of the original PPG, Craig McCraken, disliked it and made sure it never got to air in the US.
Quite a few of the voice actors of the dub also provide voices for My Little Pony: Friendship Is Magic. It's oddly appropriate since that show's creator, Lauren Faust is the wife of Craig McCracken, the man who made the original show. Specific examples are Tabitha St Germain, Cathy Weseluck, Kathleen Barr and Maryke Hendriske.
Science Marches On: This is a 2006 series. Why is the major, obviously on the breaking edge of chemistry, scientist still using FLOPPY DISKS?
