Miss Independent vs. Spider

So I think you all know I don't like spiders, read: I'm terrified of them.  My legs are still shaking.  This spider was on my couch tonight.  It is thick and about the size of a half dollar.  It is now suffering a slow death by suffocation in a cup covered with a bag and secured with a hair tie in the garage.  My independent woman skills are really coming along...  I handled the situation without freaking out...  I only screamed once...
