YouTube Poops.

[Nicolas Sarkozy]

Didn't 1up invent these?

Oh, man. No.

[potthole]

Maybe I'm just getting old, but I don't really seem to find these to be very entertaining.  I've watched all the ones linked/posted in here, and they just don't really appeal to me.

To finish Razr3d's answer, this dude named SuperYoshi invented them with this one: I'd Say He's Hot on Our Tail.  Here's the original:

I just posted this YouTube Poop of mine.  It's called, "Hyrule is Attacked by Gheg."

My newest creation! It's called "Inaccuracies In Youtube Poops," where I compile errors said by the characters commonly used in YTPs. Enjoy!

Meh. Some of these can be deeply hilarious, if executed correctly. Sadly, random does not always = funny. More often than not, as shown by every Joe Bologna with an animation program, it can be ear-bleedingly annoying.

I also predict that by the end of 2008, the biggest scene on the internet will be Danielle Radcliffe gasping "Snape killed...Dumbledore."

EDIT: Whoops. Daniel? I dunno, I kinda liked the first way better.

That was great, man!  +1.  I especially enjoyed the Super Mario Sunshine music from the warped toy-box levels.  I also enjoyed the little thing you did with Edd there.

More like:  "He killed Dumbledore!" shouted Harry.  "You *******!" exclaimed Ron.

I finally made a Youtube Poop. It's of a kid playing on a playground. I found it on the computer, so I poop'd it.

It's just as much as a YouTube poop as MrSimonAlt's musical things are.

Anyone who lives near there must eat at Mama Luigi's!

I also think there's a Krusty Krab restaurant...
