Because he has a huge erection on top of his head!!

Note that void feeling. Play around with delaying or not running through with incessant urge to fill the void as you say. Get curious about the incessant urge to post. Watch it arise and see if you can't notice when it ends without giving in to it. Are there any momentary gaps with the feeling of 'void ness'?

Also, I don't get it. German humor?
