It sings!!!?

My refrigerator can sing!! Don't play play man..

My refrigerator is kinda old and it starts to sing everytime it gets bored.

I am not joking.
You can come over to my house of an entrance free and witness it yourself.
It does not sing very often but it sings at least 2 to 3 times a day.
Whenever the opera show starts, we have to open the refrigerator door and shuts it to stop the singing.
Cute eh?
Special eh??
How often do you get this kinda refrigerator?
Mine is special haha!
