Don Lapre — the boyish infomercial shyster who lulled millions of insomniacs into pants-wetting states of catatonia via the relentless repetition of the phrase "tiny classified ads!" — has committed suicide inside an Arizona prison cell. Lapre, 47, was facing 41 counts of conspiracy, mail fraud, wire fraud and promotional money laundering in connection with his latest snake oil scam, "The Greatest Vitamin in the World," which parted 220,000 suckers with $52 million.
