We all know that there's probably nothing madder than a mad Australian, right? You with me, mate? Well, here's a video about a mad Australian named "Neg", and Neg goes about knocking on the doors of complete strangers and seeing how long he can keep them standing there and talking to him.

The last door he knocks on in this video appears to be Olive Whatnoll's door...and she gives him what for!

Knock, knock, knockin' on Olive's door!
