I remember hearing an interview with him many years ago, and he shared a story about the shenanigans he got up to as a kid… he was into phone phreaking (used to be you could control the entire phone system by playing specific tones into any phone) and reprogrammed the phone system to think his friend’s home phone was a pay phone. His friend’s mom would try to call someone and the phone would ask her to deposit 20c. She was furious, and sent her son over to demand he fix it immediately.

I always thought that was one of the best pranks ever. RIP to a legend.
