Set up enough chairs for each person in the group minus one. Face the chairs inward and have everyone sit down, minus the first person who is “It” (“It” being defined as the person instigating the game, as follows).
The person who is It approaches anyone in the group and asks, “Who is amazing?” upon which that person has to invent a qualifier for those who are amazing. For example, that person might say, “The most amazing are people who own dogs.” Or “the most amazing are people that are wearing socks.”
At which point, everyone who owns dogs (or are wearing socks) gets up out of their chair and dashes off to find another empty one. It will also be looking for a place to sit during this melee.
Whoever is left standing is the new It and goes on to ask another person, “Who is amazing?”
