It’s Memorial Day Weekend and the unofficial start of summer. Most of us will be out soaking up the sun and partaking in many libations. But for those that have nothing to do or are just too lazy to leave their homes there are a ton of marathons to watch.  Entertainment Weekly has a list of all the marathons for the weekend. Some highlights are Adventure Time on Cartoon Network, Sex & The City, on Style Network and James Bond movies on G4.
