Apply for a Job with the Railroad

Fred was applying for a job as a flagman/switch operator on the railroad. The chief engineer was conducting the interview.

"What would you do if the Northern Express was heading north on Track 1 and the Southern Central was heading south on Track 1?"

Fred quickly answered, "Well, I'd call my brother."

The chief engineer just sat there for a second. "Why would you call your brother?"

"He's never seen a train wreck before.".
