Oh wow, I would have died!
The worst thing my little girl has thus far said was in private. I was clipping her toenails, and she said she wanted to cut mine. I told her mine were thicker and stronger, harder to cut, and that unless I washed my feet first probably smelled a bit cheesy
She said; "But mummy, I want to cut the cheese".
She had no idea why I went myself laughing.
