We might have watched this video of people racing in T-Rex costumes a few times and we will also have to admit that we laughed at this a little too hard. A video has gone viral of a foot race featuring about two-dozen people wearing giant inflatable T-Rex costumes.It was at the Emerald Downs Racetrack in Auburn, Washington . . . and it's pretty funny. The runners were from a pest control company. We aren't sure what's the funniest part...the look of all those T-Rex running like their lives depended upon it, or the guy who is calling it like a real horse race. Check it out and see if you can figure it out!
