Simon & Simon, on CBS

This ran for eight seasons, from 1981-89. Rick and A.J. Simon were brothers who ran a detective agency. They were very much an odd couple, as Rick (Gerald McRaney) was like this maverick cowboy kinda guy, and A.J. was more of a socialite type. Anyway, I don't remember the show that well, but it was cool and funny and I suppose it'd be fun to see it again sometime.
