The "leave me alone!" machine
The actual title is “The Most Useless Machine EVER!” but I thought I could spice it up with a side of reality, it kinda reminds me of me when somebody is trying to wake me up xD
Some of the better comments so far:
I might as well build one and place it in a mall, I wonder how many people will try to press the button ’till the end of time xD
