I just watched Undertaker mention something to Triple H about finding out what 18 other men have found out before him but wouldn't this be incorrect?
Kane and Shawn Michaels both faced Undertaker twice so that would actually be 16 other men.
If you add the fact that Triple H faced him 10 years ago and Undertaker is currently addressing him then that makes it 15 other men.
Then again, Undertaker faced both Big Show and A-Train at Wrestlemania 19, so with one extra man that would make it 16 other men once again.
Adding Triple H back in because of Wrestlemania 17 makes it 18 - 0 against 17 men.
Yes, I've had this much time on my hands and have thought way too much about this. Then again, WWE rewrites history so many damn times I don't think they even know their own records.
