HOW TO BE THE PROPER FIFTH WHEEL

  1. Laugh really hard at the movie y'all are watching, so the couples can laugh and giggle about couple things without feeling awkward like if you could hear them.
  2. Mooch off the food they are sharing, so they know you feel totally comfortable amongst them.
  3. Sit on the couch WITH them so things stay kosher.
  4. Cry silently into the blanket you guys are sharing.
