The supermarket near our house has an automatic mister to keep the produce fresh. 

Just before it goes on, you hear the sound of a thunderstorm.

When you approach the milk cases, you hear cows mooing. 

When you approach the egg case, you hear hens cackle. 

At this point I have been too afraid to go down the toilet paper aisle

A: Nothing, it just let out a little wine.
