Spaced, Season 1

Mike:
In 1994 while on weekend manoeuvres in France, I commandeered a Chieftain tank without the permission of my immediate superiors. I then attempted to invade Paris. However, en route I stopped off at Disneyland Paris, or Eurodisney as it was then called, and was subsequently apprehended on Space Mountain.

TA Officer:
Do you have any explanation as to why you might have done this?

Mike:
Well sir, at the time, I was suffering from serious emotional problems that had clearly affected my judgement. I had immersed myself in a fantasy world of my own creation and as a result I became very insular and uncommunicative.

TA Officer:
Why do you think that was?

Mike:
[Shrugs] I dunno.
