Hornswoggle
On July 22, 2007 at The Great American Bash Hornswoggle won the WWE Cruiserweight Championship. The other people in the match and commentators did not know that he was a participant in the match until the pin and he was given the belt. This made him the first person with dwarfism to win a Championship in WWE history. Hornswoggle is both the lightest and the shortest wrestler to win the Cruiserweight Championship in WWE history. He is also the smallest wrestler to win any title in WWE.
