Hey, you guys joke, but I have actually done this on a number of occasions..
We'd sign the new client out, then walk over to the plane, with family following.
The trike would already be waiting outside the hangar, and I would immediately go into this kinda blah blah routine run on "ok this is the throttle and to take off you just apply full power and then as you leave the ground just adjust the power to kinda keep you in the air and it's pretty easy to steer, you know, you'll kinda figure it out, you know, don't worry, thousands of people have done it from little kids to really old folk".... WELL, I gotta tell you, the absolute look of terror on the hapless client to be is priceless.........

And you know, I'd kinda look at him and say, "any questions, and Oh! don't forget the seat belt".....
The pressure that used to bear on the poor fellow because I'd just said that "thousands have done it", and I know that he knows that he just is Fx@!&*G clueless and I know that he knows that he is going to lose 'face' if he chickens out and MAN, the intense energy that is flowing around in those few moments is priceless
Needless to say, when I say "would you like me to come with", the poor F*&^%$# nearly kisses me..........
Cheers.
