MONSTER DAD BOOK???????????

I was flipping channels and I think I ped READING RAINBOW or some such show. They were reviewing a book I think was called MONSTER DAD or MY DAD WAS A MONSTER. The guy said it was a story about a boy who had an unusual looking father. When I looked the dad looked like a big burly biker. I can't find the book anywhere therefore I think I have the title wrong.
