#3. The Hardcore Championship
20 years on from the Attitude Era, if you tune in to WWE programming today, and you'll see wrestlers scrambling everywhere to claim the 24/7 title.
With its champion at risk of being lynched and pinned anywhere, any time - so long as the opportunist going for gold has a referee to hand - the 24/7 championship is one of the more unique offerings of WWE's programming.
The concept is nothing strange or new to anyone who grew up in the Attitude Era, however. Back then, they had the Hardcore Championship.
The Attitude Era's craziest title - the Hardcore championship
It was precisely the same principle as the 24/7 gold - the titleholder could be beaten anywhere and at any time, but the Hardcore Championship offered, shall we say, a little more physicality.
From steel chairs, to pipes, to ladders and fire extinguishers, everything was legal in a Hardcore title match. The championship revolutionalised that level and style of offence and wrestling that had previously barely existed.
Mick Foley, The Big Bossman and Crash Holly were all among the famous names to have held the title.
