The Top 5 at 7:45 is identifying the worst Halloween costumes.  My job on Halloween is to hand out candy so I see all the costumes.  Some are not inventive and kind of boring.  That's why some of these are bad.

5) Zombie (not real inventive)
4) Ninja  (seen it too much)
3) football player (Viking players arn't scary)
2) Scream face
1) Ghost
