For your entertainment....
Since I have such a hard time getting people to watch or read Detective Conan because of it's length, I've decided to make a list of important episodes.
A little explanation before you start browsing it: if it has brackets around the episode numbers that means that it hasn't been subbed yet. Also, I'm feeling a bit too lazy to put it into table format, and lj doesn't really like my tabbed format, so it all is kinda squished together...

Almost all of the subbed episodes/movies/ova's can be found available to watch online in awesome quality HERE. EDIT: stage6 has removed all of the dc episodes. Sorry, guys. Many of the episodes are now available on Anime Crazy. Be sure to check them out there while ConanTV is still being put together~!
Edit: It's now in table form and has episode titles! That took far too long, but thankfully I only have to do it once. ^^
A little explanation before you start browsing it: if it has brackets around the episode numbers that means that it hasn't been subbed yet. Also, I'm feeling a bit too lazy to put it into table format, and lj doesn't really like my tabbed format, so it all is kinda squished together...

Thought I would add this for an extra bonus:
Almost all of the subbed episodes/movies/ova's can be found available to watch online in awesome quality HERE. EDIT: stage6 has removed all of the dc episodes. Sorry, guys. Many of the episodes are now available on Anime Crazy. Be sure to check them out there while ConanTV is still being put together~!
Edit: It's now in table form and has episode titles! That took far too long, but thankfully I only have to do it once. ^^
