Second son runs up to me breathless.
“Mom! I killed [first son]!!”

“oh really?” I reply, “what are you gonna do next?”

“BATTLE [first son]!!!”

first son calls from other room, “you can’t battle me! I’m dead!”

second son carefully thinks this over. Then screams, running down the hallway

“Oh no! ZOMBIES!! AUUUUUUUUGH!”
