Thanksgiving,
Everyone helps in the kitchen, peeling potatoes and putting it all down the disposer. They don't use a lot of water, just keep putting the peels down the disposer.

Gee, next thing you know, the sink doesn't drain, and we have dishes to wash for 35 people. Someone gets the bright idea to put a hose down the drain, Now we have smelly water everywhere, and of course, the sink "DOES NOT" drain.

Well, stack the dishes and wait for the plumber the next day.

Next time, use more water to float those peels away.
