I don't know how last nights was the best show in 10 years...
I don't even recall laughing, maybe a chuckle a couple times, but I did not watch the entire thing. I turned it off after the weekend update.
I guess mine was technically when I was 5 or so. It was a summer day-camp thing. We had a field trip to the movies and one of the girls just kept chasing me around until I kissed her.
But the more accurate one would probably be when I was 15 or 16 with the girl who ended up becoming my first girlfriend.
