What's your earliest Halloween memory?

dressing up as kink kong in my first costume

Being dressed up. 

My mother screaming when she caught my uncle doing something "very bad to me" as she described it to me. I was 4 at the time. I later learned he was sexually abusing me. It was her step-brother. She turned him into police but he had gone missing. He committed unthinkable crimes in the 6 years after that before he was captured. For what he did to me he got 4 years in jail but for his other crimes he was sentenced to death. He was executed on November 21, 2012. He showed no remorse and I believe he is in hell for sure. He was executed for 3 of the 4 murders. 

Watching Simpsons Treehouse of Horror.

I don't know about earliest but I sure as hell have plenty of good memories of the sexual kind with the ladies during the holiday. I'm telling ya, it is one of those holidays were the ladies let loose on their inhibitions. you can dress up and down as whatever you like and the ladies just get all frisky and loose if ya know what I mean. I remember Halloween 2008 for example I was chilling with my friends at a costume party in Vegas and I banged this cute blonde broad who dressed up as Lady Gaga. It was ******* awesome! We went up to her room at the MGM and I banged her against the window overlooking the city. We then freshened up and went back down to the party. Just like that. 

Being mad at my Mom because she wouldn't let me go trick or treating with my costume on and no jacket because it was cold.

Grade school, maybe 5th grade. Didn’t have one of those plastic non-flammable full body costumes so I got a fake beard and dressed up as a wizard. 

Lamest costume in the class. 

Bobbing for apples at a halloween themed party, I was about 5 or 6. I also remember wearing a Chewbacca mask for my costume.
