when I was in my late teens and early twenties I belonged to a young adult group that met every Sunday evening in a church basement - we used to have a Halloween party every year. I bet my friend Frank that he would not recognize me.
At the time I pretty much was the makeup department at my college theatre dept
I used nose putty to build up my nose, gave myself a swarthier complexion with pancake makeup, gave myself a beard and moustache and bushy eye brown with black crepe hair and put on a short black wig, then I put on my brother's olive green work pants, my dad's old army jacket and my brother's work boots
the room we met in had two entrances , I came in the back one and saw Frank sitting on the couch facing the front entrance. He was busy telling everyone about our bet and explained it didn't matter how I dressed because he knew he would recognize me because I was the one assigned to bring the cake!
So I sat down next to him on the couch and waited silently.... about 5 minutes late r my brother came in the front entrance (carrying the cake I was assigned to bring) and Frank told everyone - Ok she'll be next!... then he waited and waited and finally asked my Brother , "Hey where is your sister?"
"Sitting next to you !"
All in attendance agreed I won the bet
