Panicked phone call from a jeweller who wanted to know how and why '[their] domain was in my email address'; think he sort of understood once I explained, but still said something like 'can't be too careful in this business' - well sure ok but what am I going to do with.. oh nevermind!

Password lockout/reset over the phone, reading my 100ch 'memorable phrase' as generated by pass... Gave the guy a good chuckle, and no he was not willing to concede by the umpteenth 'upper case A' or 'backward slash' that I obviously 'knew' the phrase and could surely be relieved from reciting the entire thing... I use shorter ones now.
