Teddy was a character on the TV sitcom Full House played by Tahj Mowry.
Teddy is Michelle’s first best friend. He accompanies her when she needs a buddy to sneak out and see Danny with when he goes on a date with Vicki in mid-season 5. He is also the one Michelle runs away to once later that season. He moves away in "The Long Goodbye," but when his dad’s job moves him back to the area, he returns. He is the typical best friend a child that age would have, and he and Michelle even consider trying to be boyfriend and girlfriend in third grade. However, they try too hard to copy what Stephanie’s magazines - and, impliedly, Stephanie herself - say is appropriate, and find that it’s no fun for children their age. So, they go back to just being best friends.
