A young boy is playing with his train when his Mum overhears him say "All you b**tards gettin off, F**k off. All you tw*ts getting on, F**kin hurry up..!!"
His Mum goes nuts and sends him up to his room until he learns to be nice to the passegers.
When he starts playing again 2 hours later she listens in and hears him say "Those disembarking, mind the step and have a nice day, and those boarding, enjoy your journey".
"Those of you upset a the 2 hour delay can blame that fat cow in the kitchen..!!"
