One time my friend and I were road cruising for rosy boas and hadn't seen anything all night. We spotted a largish snake on the side of the road. I yelled "Boa!" and jumped out of the truck, got my foot caught in the seatbelt and fell flat on my knees. I ended up catching the snake and it turned out to be just a Glossy Snake, which were pretty much a dime a dozen there and not worth the fall.
