I counted the number that were upside down in the packet from 1993 - 1995 of each one eaten.

From memmory it was 83% upside down. Went through a lot of Freddo's in that time because they were used as equivalent of $10 in all betting at uni (even though they sell for 50 cents). Maybe you had to be there! Geology had a lot of long boring mini bus trips to look at rocks in the field, it was nothing to be gone for a week and cover 2500km. So we bet Freddo's to fill the time in, on things like:
* number of cars in the next 10 minutes
* colour of the next car
* number of dead skippies between two towns

Bus driver was adjudicator, adjudicators word was final.

Actually compulse counting it is a very good indicator of Asperger's Syndrome. Which I unfortunately/apparently I also show other indicators for. When I worked on a seismic exploration vessel I used to be able to calculate (in my head) the speed in km/h or knots just from the shot blast sequence without use of a clock. Just counting in my head.

Even better that that was Skid, I worked in a data room with 15 dot matrix line printers for over two years that used to spit out regular data but each printer had its own pattern. Skid worked in the same room for over 10years. You could turn any printer in the room to standby, blind fold Skid, walk him into the centre of the room let him listen to the room for 30seconds. And Bang, he would be able to tell you which printer it was. This was in a steel ships hull, with noise bouncing all over the place. It was his little party trick he won many, many, many bottles of red wine, every time someone new came on board they would be done over by Skid the freak.

Skid said it was easy. You just listen to the printers talking to you each one thas a sentence. To my way of thinking when the machines start telling you stuff it is a sure sign you have been at sea way too long.

Back to the topic I only have the R so no taco... and no idea what revs are happening.
