I have two.
August, 2010 - after a month off of golf due to metal wellness rehabilitation, I played Whstling Straits. I played really well on the front and shot 35....then I started drinking vodka lemonades....30 shots later (5 birdies, an eagle, two pars and a bogey), I carded a 65. Haven't sniffed that score on any course since.
April, 2006 - was in LA for an ABA meeting. We escaped for the day and went over to Riviera with my boss and two other gambling/drinking golf enthusiasts. My boss and I were playing the other two....and we were getting thrashed on the front despite my 39. We were down 185 dollars that I didn't have. So.....we started drinking Amstel Lights by then dozen to mask the pain. I birdied 10, eagled 11, birdied 12 and 13......shot 31 on the back for a 70....and three putted 18 for a heartbreaking bogey. Needless to say, we also won the game by a pretty large margin.
Both rounds I was laughing and smiling the whole round....I guess there is something to enjoying yourself on the course. I can't wait to get back to both places.
