Since a desire to do this has come up here on meta a few times before, I wrote a few short scripts to search through the database dumps and generate the answer/comment thread associated to it. So far I wrote three. One of them searches for comments with votes above a certain threshold (this is what I got for the threshold 40, for instance). Another searches for a given piece of text in MO (both posts and comments) and will display the associated threads. The last one lets you search for a given user and shows all threads in which he or she was involved.
If people find these are useful, I will be happy to improve or expand them. I should add the disclaimer that I am not a programmer and was just having fun, so they should not be taken too seriously.
