#Lava

*Carefully* place a bucket of lava by your <strike>victim</strike> innocent bystander. Once they are aflame, pick it up again so it doesn't spread too far!

#Fire

Light them on fire with flint & steel. You can punch out the flames immediately to minimize collateral damage.

#Suffocation

Carefully dig a hole directly beneath them, and fill it in with sand/gravel.

#Drowning

Construct a water flow that drowns them (look up some mob traps). 'Accidentally' knock them into it.

Remember: **It's not you, it's the hostile environment.**
