Plastic Mug

The plastic mug that sits on my desk every day. Had a hour of time at work with no supervisor to give me another project, so I decided to practice my surface modeling, and the most complicated curved object in sight was my mug. Because I am sure someone owns the design of the existing mug, mine is just a close copy with eyeballed dimensions... If you open the file and the hideous surface modeling technique makes you want to vomit, please post and tell me what I did wrong/how to improve!
