Are we revealing our age through exploits now? How about "using gopher on a university library terminal to access a site that launched a telnet session so you can check your out-of-state college email over the summer"?
Allowed free shell accounts and the college board in GA offered free local dialup access to a Gopher server (Peachnet).
I had a terminal script that navigated through the Gopher menu until I could get to Nyx.
