Biologist jokes

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."
