Are there any videos on youtube you used to occasionally go back to which you can no longer find?

[6ft4]

I mean ones that you really should've downloaded so you could have them saved for ever but you never bothered to do it then one day you searched it up as you usually do and suddenly you can no longer find it?
I'm talking more so about those random gems of videos you find on some channel who just uploads stuff as a hobby that you could never have found otherwise
as opposed to some video from one of your favourite career youtubers
