I can't even express how much joy i've been getting from listening to these fucking Ventrillo harasment videos.
Essentially some random guy sneaks into private vent channels, records samples of the people in there talking, plays them back randomly and confuses the shit out of the vent peeps.
This one is by far the best because the channel is full of some rednecks playing WOW.
Watch it, if you like it, there are a shit ton more. It's called Ventertainment.
