So a new thread needed to be created for basically the same purpose?
The new video was unique enough in its own right to warrant a new topic if he wanted to make one, in my opinion.
Secondly, are you seriously expecting every user to search very methodically
JUST TO MAKE SURE there aren't any other topics with a similar relation past the first few pages?
That's an unfair expectation.
If it's a megathread, I can understand that point, but here it's just showing off a funny video.
