Yeah, well, why not? Here’s a gila monster. In fact, it’s an irritated gila monster who wants to bite the gavone with the camera. I got bitten by my monitor lizard once: about the size of an adult gila monster. It was like getting a car door closed on my hand. And she wasn’t half as mean about it as she could’ve been.
Point is, even if they weren’t venomous, a gila monster could still make you wish your father had never met your mother. So don’t mess around with them.
