Family bonding

So my cat believes the weekends are for "family bonding"...all day, everyday.  The moment I get on the couch in a position he believes could be comfortable for him...he's on me like peanut butter to jelly.  He does make nap time better, but he also thinks naps should last all day.  Needless to say, I haven't gotten much done today and am now beginning to believe I have grown a tumor on my chest...
