A Funny Thing

A man with and his son walked before me were walking infront of me/ahead of me.

Suddenly, I heard the little kid say, "Dad, the swimming pool water tastes too bad.

Haha, that's funny. Is the swimming pool water drunk alcoholic?"

I'm assuming the last three sentences meant to be the child's quote. You will need to adjust the end quotations marks if I assumed incorrectly.

Other ways to say the last sentence:

Is there alcohol in the pool?

Is the pool water spiked?
