We've all stood in lines but most people stand quietly and try to ignore everyone else. But if we stand long enough people strike up conversations and eventually start maneuvering for a better place in line. But what is the ritual really for?

The Cockroach Theatre and the Nevada Conservatory Theatre are reviving the play and it will be performed at UNLV and downtown at the Cockroach's home.
