He wrote that he suspected the man was in his 20s and was either homeless, drunk or sleepwalking - or all three. The smell of body odour confirmed Prager's suspicions. "There is no TP [toilet paper] in my bathroom - wonder if that is complicating things for him - was gonna wait for him to come out and kick him out," Prager wrote.

By then, many of his Twitter followers were recommending that he call the police but Prager was contemplating whether to do that or "find a blunt object before opening the door". He had a gut feeling that the man was harmless. Prager wrote 15 Twitter posts over about an hour before finally deciding to confront the man. He put on his shoes and picked up a weapon. "Debating calling cops but just feel it's not needed for some reason," he wrote.

In true geeky web 2.0 style, Prager set up a live video stream via Ustream.tv and his followers watched while he dragged the man - who had passed out - from his bathroom. The video, which has now been published on YouTube in two parts (part one, part two), shows Prager escorting the man, who by then was not wearing pants, out of his apartment. But before they reached the door the man collapsed on Prager's bed.

"Get your ass out of my motherf---ing bed. You gotta get up, you gotta get up, and if I don't stop yelling at you you're just going to pass out, I can tell - I don't even know who you are dude!" Prager yells in the video. "Dude, isn't this a little weird for you? Maybe it's normal, but this isn't normal for me." The man is unresponsive for a time before he finally gets up and walks out the door.

The pair can be seen talking for a while, but Prager struggles to extract any intelligible responses. Prager then locks the door but the man tries to open it again for several minutes, before walking away. Prager's Twitter followers said he was stupid for being too nice to the man and not calling the cops. Some questioned whether it was a hoax but Prager assured them it wasn't.



"Ok - I think the drama is over - intruder is out - door is locked - think I finally need some sleep," Prager wrote in his last tweet before turning in for the night.
