Anthony Mesa, 22, was sentenced to six months in jail and two years of a form of house arrest for urinating in the bottle of Mountain Dew and must also periodically take a urine drug test. Mesa said Wednesday, however, that he has a condition called shy bladder which affects his ability to urinate in public and therefore to take the drug test. He had failed to take a court-ordered test Sept. 19... "Anthony's little prank has taught him a great deal, and the irony of it all is that peeing was what got him trouble in the first place, and now not being able to is getting him trouble again," Mesa's mother, Denise Hislop, wrote to court officials... Mesa, a former convenience store clerk at a Pix store in Deltona, pleaded no contest to tampering with a consumer product. A construction worker who purchased the drink he urinated in began vomiting after drinking the product.
