Either way, and OFFICIAL(!!!) Guiness World Record Monkeytail gathering happened in Tel Aviv, Israel with 244 Monkeytails. Your brothers at TheMonkeyTail.com salute you as we wipe tears of pride from our eyes. [Sidenote: C'mon, 'Murica. Get your shit together. These awesome Israelis are making you look foolish.]
Looks like they even hired a graphic designer for the branding of their event. That is literally all we can figure out from the Hebrew(?) when we tried to research their protomotional image. Many props to the designer, Tamar. Check out his Monkeytail work >> here.
We found a blog with some great pics of the event. These guys know how to do it.
