From Redditor u/wunabesk8r:
When I was a kid, my best friend at the time told me that you could go behind the ski ball machine and there would be a large opening underneath that would allow you to crawl to the backside of the front/ticket delivery area. And, if you made it there, without being noticed first of course, there would be a little button you could push that would print tickets.....easy money.
So, the next time I was at Chuck E. Cheese I put my younger sister on lookout duty/ticket collection duty and tried it out. It was a tight squeeze because they put the ski ball machine so close to the wall, but God damnit I made it behind. And, lo and behold, there was a large opening underneath the machine. So, I shimmy myself underneath, and, I swear, it felt like being underneath Christopher Robin's bed. There were: tokens, tickets and toys. And a LOT of money. Like way more than you would expect.
I continued to crawl forward, using the sliver of light that shined through the bottom of the front as my guide. And there it was....the magic button. I reached out, pushed and held the button and I could hear my sister start giggling. It was actually working. I held the button for what felt like an eternity, continually nervous knowing that we could get caught at any moment. I finally decided that was enough for this run, scooped up as much money as I could and shimmied back out. My sister and I split the money and the tickets, and ran this scheme a couple more times before, sadly, getting caught. I haven't been back to Chuck E. Cheese since.
I called my sister to confirm that this wasn't just a fabricated childhood memory, and she confirmed. We Danny Oceaned the f*** out of that Chuck E. Cheese.
