If you're like me, your friend drives in miles per hour and meaures ultrasonic velocity in inches per microsecond and it drives you NUTS!! Bring them out of the stone age and into 1970 North America by posing as a helpful Level III, then sneakily change the units setting on their Omniscan! At first they'll hate you for it, but eventually as the powers of 10 work their way through their Southern BBQ sauce blood, they will come to realize that metric is where it's at and Canadian beer is better.
