Talking a customer through configuring an email account...
Me: ok, enter you at yourname dot com
Client: the word 'at'?
Me: no, the symbol.
Client: What's the 'at' symbol?
Me: It looks like an 'a' with a line around it
Client: Ohhhhh. The monkey symbol
Me: Whaaa? The monkey symbol?
Client: Yeah... that's what it's called isn't it?
Me: Errr no.
Client: Well that's what I call it, so can we just refer to it as the monkey symbol from now on...?
Me: Sure... *thinks* WTF?
