Oh yeah :) You also want to look into Girls! Girls! Girls! to hear Piper trying to explain it three years on, and especially the bit where Tennant presses RTD for an answer.  He's a good questioner, since he wasn't really present for the Bad Wolf stuff the first time around.  RTD is a bit lost for words.  So roughly the 8' mark there.  Tennant nails Bad Wolf as essentially a "bat signal".  RTD laughs and agrees.
