A miniature horse born Friday in New Hampshire may be the smallest ever, his proud owners say. Einstein stands 14 inches tall and weighs just 6 pounds—on the small side even for a human baby—and his owners plan to approach Guinness. "Thumbellina, who holds the current Guinness world record, was born at 9 pounds," one of the petite pinto's owners tells WMUR. Einstein isn't a dwarf, says another co-owner; he's just tiny: "This little guy is like all horses, he's almost all leg."
