Alice, Bob, and comment chaos
The Alice and Bob After Dinner Speech (1984)
A nerdy old speech about Alice and Bob has fans cheering, reposting, and arguing over the timeline
TLDR: A famous 1984 speech turned abstract tech ideas into a hilarious fake romance-crime story about Alice and Bob, and readers still love it decades later. The comments were mostly a mix of nostalgic applause, repost shrugs, and a small side-drama over a weird posting timestamp.
A delightfully weird 1984 after-dinner speech turned into a full-on comment-section reunion, with readers treating it less like a dusty old talk and more like a beloved cult classic. The speech itself is a comedy routine disguised as an explanation of coding theory, painting "Alice and Bob" not as dry textbook names but as a suspicious pair dodging taxes, plotting revolution, and trying to trust each other over terrible phone lines. For non-experts: these two names became famous stand-ins for imaginary people in tech papers, and this speech jokes that their shared backstory is basically a soap opera.
But the real action was in the reactions. One camp basically said, who cares if it’s a repost, this thing still slaps. Another commenter came in with accidental mini-drama, saying the site showed the wrong posting time and asking, in so many words, what happened here? That gave the thread a tiny mystery subplot: not just nostalgia, but timestamp chaos. Meanwhile, another reader went full spin-off mode, wondering why nobody gives the same juicy treatment to other old-school made-up computer characters like Mort, Elvis, and Einstein. In other words, the community didn’t just read the joke — they immediately started expanding the cinematic universe.
The strongest opinion? This speech is too good to stay buried, even if it has clearly made the rounds before. The hottest joke is that the fake lives of Alice and Bob are apparently more fleshed out than some real people’s biographies — and commenters seem absolutely fine with that.

- •It states that coding theory papers commonly use Alice and Bob to describe transactions and communications between two parties.
- •The speech describes scenarios involving secret messages, mail-based games, stock deals, and other exchanges to build a fictional biography of Alice and Bob.
- •Alice's communication problems include high communication cost, noisy channels, constant eavesdropping, impersonation attempts, and lack of trust in Bob.
