I once drove over 200 miles to an office in Milton keynes,as they where hosting a very important meeting and a recently installed smartboard and VC system wasent working.

I was sent into the meeting room as they just started,after five minutes of listening to this management guff from my position of head firmly stuffed in a cupboard.
The projector,board and video conference unit all beeped,whirred and buzzed into life.
I packed my kit and headed for the door,just then i was asked what was wrong with it?
“Functional transitional error mate”
and left
the security guard who escorted me back asked what that was?
“Not plugged in buddy”!!
