There's gotta be some nutball in Gotham who ended up finding a batarang one day and then the most unlikely thing happened: he found another. Suddenly, "Brian Colesonson: Bean Counter" realized his true purpose in life and became "Brian Colsonson: Batarang Collector". He bought his own police band radio and converted his vintage 70's VW Beetle into the "Batcatcher" and searches for "suspicious bat activity" . When he finds it, he counts to seven and then fulfills his calling by searching these crime scenes obsessively for batarangs. He has a few of the Robin R's but uses those mostly as coasters.
