When my nieces were younger, they had to drink water to wash down their chocolate bars

Strict dad, no doubt. ("Milk costs money, water is free" 🙄 Meanwhile he would drink a couple of beers every night)

One time when I babysat them I gave them chocolate and offered them a glass of milk to go with it. They said they only drink water, but I told them the truth: chocolate + milk = delicious

They were somewhat reluctant to try, but gave it a go anyay.
The look on their faces after the first sip was something like this:

I got in trouble with their dad, but their mom (my sis) thanked me for making them drink milk. Bc, you know.. It's good for you.
