This past week on Smackdown, Alberto Del Rio regained the United States Championship from Kalisto, giving Kalisto a one-day reign as champion (2 or 3 days in air time depending on whether you watched Smackdown on Wednesday or Thursday). Kalistos reign as champion is one of the 30 most inconsequential title reigns in WWE history, but where does it fit amongst other inconsequential title reigns? The criteria for this list are that these are one-time-only singles champions (so Wade Barrett neednt fear an inclusion on this list for his five separate inconsequential Intercontinental title reigns), and we are relegating this list to Intercontinental, United States, and European Champions. Whether or not the reign was inconsequential or not, if you win the WWE or World Championship, it means something. The Hardcore Title changed hands so often (which was the point of the title) that it could have its own list. Finally, there will be a lot of short reigns on this list, but having a short reign may not necessarily mean the reign was inconsequential. The manner in which the wrestler won or lost the championship has been taken into consideration as well. There will also be some champions on this list with very long reigns, yet still, they were inconsequential. This list will be in order from shortest to longest.
