I got a legit 12. There were several more that are borderline for me.
For instance:
I did not "spend the night" in the drunk tank, they let me go as soon as I posted bail.
I didn't buy the whole bar a round, but I did buy a table of twenty people two rounds.
I never sat on the grave of a hero, drinking and talking with him, but we tripped in the graveyard once and set off the alarm at the crematory (funny chain of events following that one).
Edit: 13. I did open and close a bar once. I moved out in the sticks with mom during my divorce and there was an old redneck biker country blues bar by her place.
Me, a Bimmer driving, nerdy/pretty boy lookin, well dressed city slicker, in what turned out to be the roughest dive that I ever was a regular in, made for some pretty damned good times! I was sorta the Frazier Crane of that place for a while. Oh, and country/biker girls can be very naughty!
