Watching people getting scared by a dinosaur will never not be funny. Except for maybe when Jurassic World comes out. Then they might get scary again.
But until then we can enjoy seeing people panic and overreact when surprised by a dinosaur in their backyard. We really don't know why the AverageBrosTV guys thought it was a good idea to do this again, but we guess the lure of YouTube fame is stronger than the potential to be maimed.
