I've been on a bit of a bender with old TV shows in recent months. My girlfriend and I watched Cheers, M*A*S*H, Full House and are currently watching Home Improvement and the Drew Carey Show. On deck are Happy Days, Star Trek TOS/TNG and Wings.
Most of what we've watched are shows we watched as kids either in broadcast or syndication. What do you recommend as shows that we could watch next?
