Crew boss

A young wildlife biologist got fired from his first real wildlife job. Upon
his return home, his parents asked him what happened.
“You know what a crew boss is?” he asked. “The one who stands around and
watches everyone else work.”
“What’s that got to do with it?” they asked.
“Well, he just got jealous of me,” the young biologist explained. “Everyone
thought I was the crew boss.”
