Igor is 7 feet, 8 1/3 inches tall -- beating George Bell, the 7'8" deputy sheriff from Norfolk, Virginia.
Vovkovinskiy was raised in the Ukraine, but moved to Minnesota when doctors at the Mayo Clinic attempted to remove the pituitary gland tumor that they believe is responsible for his great height.
The surgery failed, and Vovkovinskiy kept growing, according to my colleague Ben Muessig of AOL News.
Now, the new tallest man in America wears 24 10-E shoes, one size bigger than Bell's big boots. He lives in a house with cathedral-style ceilings, and sleeps in a 9-foot-long bed.
