Something of a daily occurance, NCIS is a great show and it seams its so great that they have "Marathon's" almost everyday. Do not get sucked in as these last for 12-24 hours and you will get nothing done.
Person 1: I'm going to work on my project *walks into TV room* EWWW!!! NCIS Marathon! *Two hours later*: Shit I got nothing done!
In short don't get sucked in.
