How you can buy anything in Iran
Gun - It's not possible to buy it in Tehran, I don't think, but go to border areas with Afghanistan. It will cost at least 2,000,000 tomans ($US2500).
Motorcycle - It's illegal to have a bike over 250cc, and most people only have 125cc bikes. (Unless you have mullah friends or are from another country.) But I know people with 400cc and 900cc bikes. The 400cc bike for example was smuggled from Dubai (4,000,000 tomans).
Stolen Western Passport/Forged Visa - This will cost A LOT but where there is DEMAND, there is a WAY. That is, for those who don't want to claim they are homosexuals or communists or have the government call them that...
Virginity Restoration - Hymenorraphy (or hymenoplasty) is a simple operation, although a pathetic idea! In the movie "khanei ruye ab" the male gynecologist suggests 800,000 tomans to a prospective patient, but I think it's way too much (see US price - $5000-$10000! or Turkish price). It must cost less than LASIK or a nose job (rhinoplasty), and those are cheaper but far more complicated operations. So if I'm wrong about anything please comment.
