I realized that “Mensa” didn’t contain enough numerals to be a phone number, and knew it must be understood that any future member would be able to figure out the next two digits in the sequence. I tried dialling MENSANE, MENSAIL, MENSAFE, and MENSAAB, but got three rebuffs and a fax tone.

Yeah, I’m reconsidering now that someone mentioned that. I’m not going to the meets, though, they get bad reviews for exactly this reason.
Edit: Uhh, looks like it’s only the US Mensa? Maybe some of the other Mensa-like things have benifits beyond the “pleasure” of their company, I don’t know.
