i was in 5th grade, and it was halloween. for the weeks leading up til now, i thought i was too cool to go trick or treating, and i hadn't prepared any kind of costume at all. 

it was about 5:00pm when i realized that i was definitely not too cool to go trick or treating, and i quickly tried to find a costume to throw together. i found some face paint  in a halloween box and made myself a skeleton, then grabbed a black under armor compression shirt along with "my" pair of black under armor leggings, which i usually wore under my uniform for cold football games.

my parents were at a halloween party and my older brother got stuck watching me. i didn't bother him though, i just slipped out the back door and headed downtown, where i knew all the local businesses would be giving out pounds of candy.

it's a small town, and it was about 3 blocks to my destination. the streets were full of parents and their kids, and they all seemed to be staring at me as i passed them. 

i didn't care though, and i made my way through downtown and scored a pillowcase of candy. everyone was still staring at me as they passed me or handed me candy, and i couldn't figure out why.

until i ran into my cousin, and my uncle larry informed me that my pants were see through.

in my hurry to get candy, i had grabbed my sister's dance leggings, which were about as thick as a pair of panty hose. 

i was a skeleton with a 4th grade penis for halloween that year. which if you think about it is pretty scary.
