15-16 years ago a friend was trying to get a game show off the ground (he didn't). They were shooting a pilot & he asked me to be on one of the teams of contestants.
We were told each team should come up with a name for itself & an identifying "look" (an outfit, shirt, hat, badge, whatever). I suggested my team hie itself hence over to the Golden Apple on Melrose and buy a buncha Batman T-shirts.
We would call ourselves The Bat Shirts.

They were not amused.
