Firefly Trailer???

I was at a bar last night and Fox was on showing a game or something. I wasn't really watching, but out of the corner of my eye, something science-fictiony was going on and when I looked up, I saw a bit of explosion/spaceship/etc. going on then the screen "Firefly on Fox Fridays" or something like that. Missed it! And I can't seem to find in online anywhere, either. Any ideas?

I checked there before posting as well as Google but nuthin'. Lots of footage of Joss talking (which is not a bad thing) but no real "trailer" unless those still shots at the beginning are what I missed on the telly. In which case...ugh...want real trailer! Maybe as we get closer. Thanks!
