Hey, I'm looking for an episode that has lots of humor/funny events. I've seen every episode, every movie, every OVA, everything. But I can't remember any funny episodes. Please, recommend some for me. Thanks!

How about the latest Magic File?
Magic File 5 - Niigata~Tokyo Souvenir Capriccio

Hmm...I think movie 8 (magician of the silver sky) had a few funny moments such as when "Shinichi" comes and everything. And not sure if this counts but the Magic Kaito episode is pretty funny too :)

Usually episodes with Heiji are also pretty funny but I'm not quite sure which ones...so try them? You can see which eps he appears in: link

Sorry for the vague answer, so many small funny moments just throughout the whole thing I guess :) Hope this somewhat helps ^^

for me, I think in ova 10...

A lot funny events between Kid & Conan are in movie 14...as for me...
