I don't think my reply will be anything useful, but as to me the most craziest bug is metabug, i.e. when system doesn't provides any means to debug things. :)
As for regular bugs .. it is quite hard to remember anything i wasn't able to deal with, given enough time & effort, and then emphasize single case over the rest. And since human brains tend to forget unpleasant things, there's not much details to tell and remember.
