Now he appears to have proved it after claiming he has fathered a child.
Easterday, 35, was born with a rare condition called sacral agenesis, which prevented his spine from developing normally.
When he was just six months old, doctors amputated Kenny's legs and used part of his shinbone to complete his partially-formed spine.
Kenny is so small he can fit inside a suitcase but that hasn't stopped him playing pool, bowling, working - or having a love life with fianceé Nicky, 33.
In an American television documentary, he and Nicky revealed that they were together seven years ago - after which she became pregnant with her daughter, Desiree.
The pair are soon to found out if Desiree is actually Kenny's child. And they hope to start a new family to join Nicky's two children.
Kenny's greatest dream is to have a child, he revealed in the documentary.
