Most of America knows Tim Allen best as the genial, lovable sitcom dad from Home Improvement and his current red-state reassurance vehicle Last Man Standing. But if you were looking for coke in Kalamazoo, Michigan, in the mid-70s, you might have known Tim Allen as your drug dealer. Enough people knew him as such that in 1978 an undercover officer set up a sting operation that might have landed Allen in jail for life had he not snitched on nearly two dozen other dealers.
