29: Hissing Noise
This driver came into the shop with a weird hissing noise that was coming from under the hood. The car had been sitting for a long period and the driver hadn’t opened the hood, so he got himself into some trouble under those circumstances. Underneath the hood, there was a visitor who just happened to be a rattlesnake, so it is important to check all the areas in your vehicle due to the fact it may end up saving your life (via Reddit).
