Hmmmm...
I agree with Growing Pains, I always sang along! Others include: (these may not be the BEST theme songs, but they're the ones whose words I remember!)
1. Cheers: best theme song of all time. Who doesn't sing along to that??
2. The Facts of Life (haha!! Admit it, y'all know the words..."You take the good, you take the bad, you take 'em both, and there you have...The facts of life, the facts of life...")
3. The OC
4. The Fresh Prince of Bel-Air
5. Full House
Again, these are theme songs I sing along to when I see them... :lol:
