has anyone else noticed that in a couple of the episodes on ME TV they used the closing theme for the opening theme? I wonder why?

I have noticed that sometimes I do hear the "fast" version that usually plays over the final credits over the opening ones,usually on later episodes.I always thought that for some reason,this decision was made by the producers during the show's original run.And now that's you've given mention to METV...WHAT A NETWORK!They actually ARE what TVLAND was originally meant to be!
