During the UN operationin Somalia you could get a Somali licence with anything at all on it for 10$.
Lots of us got them as "bar Jokes"
Mine is endorsed DC-3, SR-71, Spitfire, Mustang, Concord, Apollo Space Craft, lunar landers ( bet you didn't think there was a dual endorsement required if you planned to land vs just circumavigate the moon ) and Enterprise Class Starships all marks among others.
I don't think I would jump into a SR71 and launch on the basis that I have it written on a paper with an official stamp.
Some wags also got Somali diplomatic passports - one jokester actualy tried to use it when returning home expecting giggles all round - Officials failed to see the humour of the thing and gave him an exceedingly bad time.
