I've given your idea/request a shout out and linked it to your above post from twitter.
Personally I thought those were frequently awful and aimed at a teen/female demographic UPN thought were going to watch Enterprise, but in the end probably didn't. Aside from maybe the first few to do with the series premiere (remember they used NASA footage and The Calling's Wherever You May Go?) which I recall spending hours trying to look at on a slow dial-up internet connection.
Never anything as memorable as "Next Time on Staaarrr
Trrrrek The Next Generation" though!
