All you have to do is pop off the keys and place them somewhere else. We did that shit to eachother in my compter tech course.. It'll fuck up your typing skills if you have to look at the keys when you type. They replaced my keyboard with a fucked up one and it didn't affect my typing at all since I don't look when I type.. I didn't even notice until someone told me about it LOL. Somebody put "YOURABITCH" across the top row, which I didn't find funny because I had done it to somebody else a few days earlier.. Unoriginal bastards. Haha
