Do You Remember This Show? (Nineties Kids, ONLY!)?

This has been bothering me like crazy. It was about this kid named Bobby--he kind of had a big football head with black hair, and a brother (I think his name was Derik,) and he'd always pick on Bobby and call him "dweeb" or "dork". Also, his family would always rub his hair and go, "Nuggie, nuggie, nuggie, nuggie!" and he hated it. I used to watch it all the time when I was little, but I can't for the life of me remember the name. Can you? Late eighties kids may know, too. It was a cartoon, if that helps.
