This is the most adorable thing you'll see today. Back in 2009, YouTuber tfoust1012 took their son to the Heard Natural History Museum's animatronic dinosaur exhibit. Apparently Zack was a huge fan of dinosaurs, he'd just never seen one in person, or so lifelike. His reaction is absolutely brilliant.

On second thought, maybe the title of this post is wrong. I can't decide... is Zack's decision to run fueled by panic, or is it a calculated move to put an easier, less evasive meal between himself and the T. Rex?
