There was a pretty serious drought when I was young, in the 80's and my mom and dad used to have to go get our water from the "Water Buffalo" which is a Bulk Potable Drinking Water company. I thought they had brought in actual water buffalo, the animal and people were getting water from them, like milk from cows.
I thought this until I was in COLLEGE and got into an argument with my roommate about it because she didn't believe me, I called my mom to prove my point and was of course laughed at.
