I sent more than one message from God by telnet to <mail server> 25. Good times!
Around the same time, someone at my school made a much, much worse semi-accidental prank. Semi-accidental because he didn't think it would work. See, the campus list serve was setup to only allow certain senders to send messages. Makes sense, only a few top administrators should be able to do that. This person theorized that a simple <smtp: from> hack, using an authorized person's email, might circumvent the restriction. He was right! Unfortunately, rather than "test 1 2 3" or something, he sent a message, from the president, that all classes had been cancelled. Had he stopped there, maybe it would have been chalked up to a prank. But he went further: The president would be using this free time to, um, entertain amorous visitors at their leisure. So, yeah, expelled. His excuse, when interviewed by the student newspaper, was "I didn't think it would work."
