I have been known to spend hours watching back to back YouTube clips from the following categories
  1. Emotional singing auditions
  2. Steve Harvey's reactions to bizarre Family Feud answers
  3. Soldiers coming home to surprise their families/dogs
  4. @FallonTonight Wheel of Musical Impressions
  5. @FallonTonight Lip Sync Battles
  6. Anything sloth related
  7. Earnest, heartfelt acoustic covers
  8. This video of Liberace, which is a genre unto itself
