Eveyone loves Raymond is based on Ray Romano's own family and comedy, while Dave's World, which ran on CBS from 1993-1997 was based on Dave Barry's books "Dave Barry turns 40", and "Dave Barry's greatest hits".

Not to bust your Ba**s, I just hated the Everyone Loves Raymond show, his wife was such a "C" word in that show. I couldn't watch any guy be constantly belittled and berated and find it funny.
