Not sure if it true, but I hope so.

Heard a tale of a jumpseater hoping on a UAL flight and went to ask the Captain for the seat, the FO said " I'll handle this" looked at the jumpers paperwork, welcomed him onboard and introduced himself to the jumper, then intoduced the FE to the jumper then said "thats the Captain, but don't tlak to him, he is a scab" all this while the Captain sat silently looking out the window knowing his place.
