Yesterday I spent most of the day with a screw driver in my hand. I built an Ikea dresser, I tightened all the screws in my house that need tightening and I built a couple shelves.
By the end of the day, and even this morning, my hand feels like it is going to fall off. Now I know why they make powered screw drivers.
In any event, I just love those Ikea instructions and I found at college humor some funny mocks of them. Here is one but there are plenty more. Enjoy.
