Everything is funnier when you're dressed in a T. rex costume

Though the Tyrannosaurus rex was once a giant, fierce carnivore, its proportionally tiny arms have today become the stuff of internet comedy gold.

Thankfully for those of us who need a laugh, inflatable T. rex costumes exist. And the people who own them have discovered that watching a T. rex try to wash a car, or operate a kayak - or, well, anything - is just plain hilarious.
