PHOENIX, Arizona (CNN) -- Basketball great Charles Barkley began serving a three-day sentence in Arizona's infamous Tent City on Saturday, jailed by the same sheriff whose autobiography he endorsed 12 years ago. Charles Barkley bristled at the implication he should be wearing stripes instead of a red-and-bue sweatsuit. "You come here when you screw up," Barkley said at a news conference hours after he reported at the Maricopa County jail. "I don't blame anybody for this situation but myself." Barkley, 45, pleaded guilty last month to misdemeanor drunken-driving charges stemming from a New Year's Eve arrest after he left a Scottsdale, Arizona, nightclub.Charles Barkley begins serving 3-day jail sentence in Maricopa County, ArizonaThe jailer is the sheriff whose autobiography Barkley endorsed 12 years agoBarkley speaks out against drunken driving during topically diverse news conference"He's taking his medicine," Sheriff Joe Arpaio says of his famous inmate
