Ferrari Mailing List: Re: birthday greetings

Brian:  Yea, the shame of it all. Not to worry though ... I tell people mine is 
a Kelmark kit car, not a Ferrari gt4. Wait til I hang the big Roadrunner rear 
spoiler on the back. You'll see...

And after all that "fleecing", you could only afford a gt4?  
Shoulda tried fleecing unsuspecting people outside the welfare or peasant
classes. ;-)

Thread hijack:

In college days I used to fleece money from unsuspecing passengers by
betting them that within the next 20 cars, there will be two whose last 2
digits match.  ie - a match could be ABC123 and DEF523.
Without punching the numbers, I think the breakeven point on this was around
16 cars.  It would very often go to at least 18 before a match.

What was especially neat is that often you could get odds, as we are only
talking about looking at 20 cars and there are 100 possibilities. Hehe.  I
usually would start the proposition that we would look at the next 50 cars,
as that should be 50/50 odds, right?
But then "for practicality" sake, it got reduced to 20.  After losing the
first bet, the victim would often want to do it again to try and get his
money back.

Hans.
