Martian Job Interview

the Martian goes for a job interview in an office. The interviewer starts with
the basics. "So, can you tell us your age, please?"
Martin counts carefully on his fingers for half a minute before replying.
"Um ... 26."

The interviewer tries another straightforward one to break the ice. "And
can you tell us your height, please?"

Martin stands up and produces a measuring tape from his handbag. He then
traps one end under his foot and extends the tape to the top of his head.
He checks the measurement and announces, "Five foot eight!"

This isn't looking good so the interviewer goes for the real basics;
something the he won't have to count, measure, or lookup. "Just to confirm
for our records, your name please?"
Martin bobs his head from side to side for about fifteen seconds, mouthing
something silently to himself, before replying, "Martin!"

The interviewer is completely baffled at this stage, so he asks, "What
were you doing when I asked you your name?"

"Oh, that!" replies the Martin," I was just running through that song, '
Happy birthday to you, happy birthday to you, happy birthday dear.....'".
