I don't really think this qualifies as humour. But...each to their own. This is a japanese prank show where..the aim is to scare a sleeping person in the most imaginative way possible. Oh and do the Japanese have a lovely imagination. Waking up and seeing Yakuza standing over you with machine guns.oooh how I did NOT laugh. Disturbing. I do not think I will go to sleep in Japan!
In case you cannot make out..in the video. The first one shows 3 guys with bazookas in his bedroom
See for yourself: Sleeping prank show!
