Is there such thing as training PAST DOMS?

This has happened to me twice. One week while I was at work (I work constuction on the road and rainy days get really boring). My coworker had a crunch contest, in which I did 1000 of them. The following day I was not sore.

Any other time I have done crunches I have always been sore.
