There should also be a Latex library (?) that makes your documents look like they were photocopied, so you can use the coffee stains and the photocopy to make it look like you spent long nights working on your assignments.

On the TV show White Collar, there's an episode where a fake (paper) case file is put together and adding coffee mug stains is part of the process.
