In fact, the 4th, 5th, and 7th vids were even posted by yourself!
You can avoid posting repeats by doing a forum search on the YouTube vid's ID -- that's the letter/number code that comes after the "watch?v=" part and before any "&list=" part as depicted below. (If that code has an underscore _ in it like your 4th vid, an "exact phrase" search on Google is required as described here )
Still, thanks for your efforts! Seeing that first vid again inspired me to make a little GIF
Love you, too
