I also double clutched my school bus. Apparently I was the only one who knew how to do it, since everyone else just pushed on the shifter and waited a good 3 or 4 seconds for the synchros to do the job. I'd get comments on how I could race in a bus professionally if I wanted to.

In my cars I usually would double clutch the downshifts as the upshifts didn't seem to help that much.
