Comp picks up sounds when mic not plugged in

[Dimyim]

I have a VisionMan GT3000 Computer. With no signifigant modifications from the specs listed in the link. However, when my microphone isn't plugged in and i open a voicerecord program, the computer still picks up my voice and any sounds nearby. This is extremely weird because of the fact that my mic's not plugged in....does anyone know why this is happening? and how do i make it stop? Any help is appreciated.

Hahaha that's funny. I think maybe you have an internal mic of some kind in your computer.
