If you look closely, there is a little opening in the false teeth where the USB can fit in, making it impossible to notice that there is even anything in there. But I do agree... OUCH
imagine an old man putting on those teeth and does not realizes it and the usb stick drive had his last will and damages it and when he dies the family is wondering what was inside the usb stick will
make a gif on imgflip about the false teeth and insert a rick roll video inside the usb and put the usb inside the computer and play the video and post it in the comment section
