Today's Random Dredd comes from the early 1990's story "Reptaur", which was recently collected and bagged with The Judge Dredd Megazine #297 (May 2010). It contains bad-assery beyond approach.
In case you missed that, to prevent himself from falling to his possible death, Judge Dredd STABBED HIMSELF IN THE HAND to pin himself to the pipe he was holding onto! It made a satisfying "STABB!" sound too.
