  Wow, 1 million views! Thanks.
Our best video, you need to see the original BBT Eye of the Tiger video to appreciate this one.
Okay, we went a little overboard on this one
Perhaps we also went a little overboard on this one
It seems so long ago that we celebrated getting to 100,000 views
We won an excellence in education award and this is the video produced by the TDSB for the ceremony.
Okay, so we think we're funny
This is where it all started
