Deer in the Headlights 

Deer in the Headlights is a great game when 2 people dress up in a 1 deer costume and walk in front of cars unexpectedly and hope to not get it.
This is best to do in a neighborhood or school zone.
Best to do at night.

Alex and Greg dressed in a deer costume, walked to the end of the neighborhood, his and waited for oncoming cars to come. Must be at night.
