To be honest I think alot of programmers copy and paste, unless it is something that they use often. If there is a module that you rarely use, or have never used before, why would you know how to use it off the top of your head? Also, some things you may be able to do on your own but copy and pasting could save you the time that it would take you to type those X amount of lines.
