There are pretty cool - found on ebay. I'd buy one but they don't ship to NZ.
How about one that says RoV Certified Motorcycle Technician ?
lol
Or
NASA Certified Space Technician
I was once NASA certified to solder space stuff. I kept asking them if I could be sent up to fix a broken satellite, 40 years later still no answer.
Thats excellent news! Our very own Certified Space Man!
