Mental health problems

I was recently evaluated for mental health problems (Some of you might say I'm not surprised ! )

Anyway, the doctor asked, "If a train was coming down the hallway towards you, what would you do?"

I replied, "get in my helicopter and escape".

The doc then said, "where did your helicopter come from ?"

I replied

Spoiler:

"the same place where you got you bl**dy train"
