Clay Aiken stinks -- literally! The singer was flying from L.A. to Raleigh, NC recently, when he off his socks and shoes and placed his bare feet on his "terrified-looking" female assistant's lap, Star reports. Nasty! But it gets grosser: Clay's rank feet stunk up the entire first class cabin! Still not satisfied with his level of weirdness, he ended up sitting on the floor instead of his seat. Can somebody tell us how this guy got to be the runner-up on American Idol?
