A hunter walks in a warden office in Maine and ask :
- I want to buy a camel hunting license.
Warden - What ?
Hunter - I want to buy a camel hunting license.
Warden - Are you drunk Sir ?
Hunter - No, I'm not drunk and I want a camel hunting license.
Warden - You're not serious, are you ?
Hunter - On the contrary, I'm dead serious.
Warden - Sir, there are no camels in Maine.
Hunter - How do you know there are no camels in Maine.
Warden - Well Sir, nobody ever saw a camel in these woods.
Hunter - I still want a camel hunting license.
Warden - Sir, we don't sell camel hunting licenses.
Hunter - I don't see why not ! For the past ten years, you sold me moose hunting licenses and I never saw a darned moose in these woods either.

A couple of years ago on the hunt me and my buddy went to the Moscow river and on the other side saw two camels. Moreover, we didn't smoke. Still don't know where they came from there - maybe from a traveling circus? But if we had a license, that day we would be with meat.

Vashper: You sure that those camels weren't from the two Islamic Terrorists who had just rode into town?

...or used them for some other nefarious purpose.
