Best Theme Song Ever?
This ranks close to the top.
Other great ones:
Golden Girls
Full House
Step by Step
Family Matters
Perfect Strangers
Charles in Charge
WKRP in Cincinnati
Mash (instrumental)
Newhart (instrumental)
Mary Tyler Moore Show
Probably forgetting some. I miss a good theme song. I think it's a great way to introduce characters, summarize the plot maybe, set the tone for the show, and it tends to help make a sitcom lasting in nostalgia.
Worse theme songs:
Seinfeld
Home Improvement
Cosby Show
Shows that have none
