most, and i do mean most 18650s have a circuit board in the endcap that manages the charging and discharging, so a dead short will generally cause that board to heat up and let out smoke. If you did manage to actually short an 18650 (it's not difficult, remove the plastic on the outside and jam a flathead in between the positive cap and the battery body, where the insulator is), it doesn't just "make a small fire, easily stamped out".
if you'd like i can go dig out a 26650 that i have where i dropped it and the board part popped off; but i am sure there are websites with pictures already.
