Some may have been concerned when Family Ties was interrupted by Happy Days a few nights ago. However, according to TV Land this was just a one night special of Happy Days and shouldn't happen on a regular basis. (I hope not)

Yeah, when I taped Family Ties I was surprised to see that I had taped Happy Days instead. The next night when I set my TV to record at the same time it taped Family Ties. So it had to have been just one night.

It was just a Valentine's special. They're not changing the Family Ties timeslot as far as i know!
