The bimbo moment

My little sister asked me what she should do when she ran out of power points in her room, while trying to hook up her computer. I handed her a power extension bar and she started analysing what's in her hands.
After freezing for close to 10 seconds, she pointed at the power plug of the power extension bar and told me that she does not have any more power points to plug into. I was stunned. Then I gave her the WTF look until she got it finally.

For those who cannot get it, you are suppose to unplug an existing appliance and plug in the power extension bar's power plug into it. Then you gained more power sockets this way.
