One of my favourites, supposedly from US special agents in Afghanistan, includes these lines:

"Last week, my group (of 4 agents) successfully overran a hard drug processing enclave and recovered a booty cash sum of US$36 million, which no doubt are proceeds from the illegal trade used for funding terrorist activities," reads the latest scam email making the rounds.

"We have since deposited this cash in a security luggage office in Kabul capital city. We do not intend to surrender this cash booty to our sector commandant for obvious reasons and we cannot take out the consignment from Afghanistan physically by ourselves as it is against military ethics.

"It may interest you to know that modalities have been perfected to move this [sic] funds to you through a security courier agency as soon as you respond in the affirmative, indicating your interest and capability to handle this transaction."
