Well, South African Nobanda Nolubabalo, 23, took a chance playing drug mule on a series of flights through Brazil and Qatar, finally being caught in Bangkok, Thailand with 1.5kg of cocaine wrapped up in her dreadlocks. For those of you who are metrically challenged, that's over three pounds of illegal drugs. Airline security "found something unusual about her dreadlocks," and upon closer inspection noticed that there was a "matted white substance," in them. 

A video of the arrest shows that Ms. Nolubabalo apparently wrapped her hair (which to a trained eye is synthetic) around sticks of solid cocaine.
