Yeah they are.. but I always have to wonder when I see people trying to sell something, like how much of them is actually real. I was reminded of this today cause I had a silly invention idea. I say silly, but with the way people are and with so many of us.. if you make it, someone will buy it. Like this tooth brush is silly in that it is such a simple idea.. mine was winter gloves with a built in lighter tip on the thumb. I can get a cigarette out of my pack with just my mouth, so I don't need to take my gloves off for that.. but I do to light it. Granted it's not like a huge hassle, but it's kind of like 'fuck.. that's effort..' but that's one way new ideas come about. A mix of laziness and efficiency.. but I'd be down to have a glove keeping my hands nice and warm and give a thumbs up to light my cigarette.
