Joke of the day

My maid went back home for a while. We have to wash our own clothes during this period of time.

Conversation between me and my sis:

Sis: How do you operate the washing machine?
Me: Oh, you just press the 'start' button.
Sis: But how do you get the water into the washing machine?
Me: ...
Me: You just press the 'start' button and the water will come.
Sis: *disbelievingly* But how does the water get into the washing machine? Where's the source of water?
Me: Just press the 'start' button and see. If you still don't believe me or the water does not flow into the washing machine, you can go take a pail and manually fill the washing machine with water yourself.
