This was reported in the United Kingdom by The Mirror, “Hilarious moment: ‘T-Rex gang’ take on Santa Claus during suburban raid,” on December 30, 2015.

Since then more T-Rex antics have popped up on YouTube, such as this one trying to skate:

And another video of a dancing T-Rex at the Cincinnati Ballet:

Plus a T-Rex on a trampoline:

The postings have come to be known as “T-Rex Tuesdays.” John Peragine gave an online report for Today, “T. Rex Tuesdays: Meet the DINO-mite duo behind the Internet sensation,” on March 8, 2016.

Eat your heart out, Barney.
