Too boring. It's time to have some fun.
Buy a voice modulator. Set it to Darth Vader or Cyclon, something spooky. When grumps yells, slide up to the bushes and say something very obscure. Odd enough to be worrisome, like "frogs in the winter reap the harvest" or the like.
Grumpy old man: "SHUT UP AVA!"
You: "Precious like hiding her bones, yeees yes yes...."
