Bump start 65 Chevy backwards

I swear this happened, but having a hard time proving it. I was a senior in high
school back in ‘73, and owned a 65 biscayne with straight six, three on the
tree.  Was sitting in an inclined driveway, and thought I’d bump start the car,
why I don’t know, but I digress. Rolling backwards, I mistakenly had
transmission in 2nd, not reverse, popped the clutch, and engine started, but
running backwards. I’d put it in reverse, it went forward, first, it went backward.
Now the topper. I shut the car off, and , I swear to god on the eyes of my
children, the car started in reverse!  The only way I corrected it, was to
jumpstart it in the correct gear. I need vindication, so please help me here Car
Gurus!
