a guy who was taking a telephone interview with a head hunter for a contract job, it went something like this:

HH: They need someone who knows C-Pound, have you worked with it?

CS: I think you mean C-Sharp, yes, i've worked with it since the early betas.

HH: No, i've just talked with them on the phone, it's definatly C-Pound.

CS: They must be meaning C-Sharp, it's the new .net language from Microsoft.

HH: No, they said explicitly that it was C-Pound they were looking for, and not to accept anyone saying they had esperience in another type of C.
