Yeah, it’s an old joke from an advertisement about job interviews gone bad. A prospective employer says from behind a desk showing his last name to be “Dumas.”
Plainly, in French, his name would be “Doo-mah.” It’s usually translated into English, however, as “Doom-iss.”
Nice, that's the best part of adult interaction here, the education provided! I was indeed "missing something," the cultural joke reference. Thank you very much!
