I like the trick your mate played, I did a similar thing to my mates.
We had a ride planned and in the week leading up to the ride one mate told me he was interested in buying a new bike and was relying on me to tell him what to buy, I said we would have a few beers and talk it over on the weekend ride.
I arrived at the cabin first and set my new WR450f up on the veranda with a spot light on it, when he saw the new bike he called me all the names under the sun.
It was a wet weekend and the WR was perfect for the ride, that week he and two others went out and purchased WR's with the great discount I had organised.

Out of my depth in a puddle.
Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
