Rotary phones reminds me of a &quot;hack&quot; I was most proud of as a teenager.<p>I was barred from calling my girlfriend at night in my room, and my phone was replaced with one that was broken. My parents wanted me to be able to answer the phone, but the keypad didn&#x27;t work, so I couldn&#x27;t dial out.<p>What I <i>could</i> do, however, was rapidly toggle the receiver hook. Turns out the pulse frequency tolerance had a pretty wide range, and I became quite skilled at quickly tapping out her number. That, and the Nintendo gamer hotline. Priorities!
