Help I'm stuck and i can't get up

I was at my aunt's house one summer and she had a little girl about 2 years old. Well I decided it might be fun to sit in her high chair. Right as my aunt warned me that the top could get stuck sometimes I pulled the tray as far as it could go towards me and what do you know I’m stuck in the high chair. So after about an hour of trying to squeeze my self out and my aunt trying to unstick the top part, she finally calls her dad. He comes in with this huge toolbox and unscrews the whole thing so I finally get out. I have still never lived this one down, every summer I hear about it from my family.
