Whats your favorite way of killing of sims?

I use drowning for killing off multiple sims at once for my cemetery lot. Another method I love using is lighting fireworks off indoors. I got this idea after seeing a firework land on a child, explode, and kill them in The Sims 1. Their family was traumatized by the accident but I made it worse for them by having the dad light a firework inside his dead child's bedroom with the mime that crashed the party after the kid died. The Dad died but the mime somehow had superpowers and survived an indoor fireworks display in a room that had the doors removed. >:)
