The unit of measurement for an embarrassing failed celebrity marriage is the Kardashian.
September 2006 to November 2012
Which is 30 Kardashians.
Of course real life time compared to comicbook time are inpropotional, and could bring that number down to 3 or less kardashians considering they got married during the preamble of the Civil War.
I still believe that George Bush has brass ones for going to that wedding when he knew that Cap would be there.
