My older brother had the t-shirt from it. Then I wore it while wearing chicken pox and it became mine. I also remember begging my mom to buy me the cereal that was basically overpriced Captain Crunch.
I was the older brother who took my 5 year younger brother to see it. Also had the T-shirt. I'm not really sure where the t-shirt went.
If I didn't take him to the movies, we'd go down to the video store and get a couple bags of chips and rent cheesy B horror movies, like the Puppetmaster series or House "Ding Dong you're Dead."
It's still my favorite Batman movie by far. I miss those days.
