Only a ginger can call another ginger "ginger" - there's even a song about it called "Prejudice" by Tim Minchin (WARNING: definitely Not Safe For Work; nor tea-parties at the Vicarage, or within earshot of your dear ol' granny). Although, now you know what it's about, it actually ruins the punchline of the song.

Panel 1: Isaac and Major Tom are confronted by a large robot with a freaky female head.

Robot Messenger:

Major Tom Cobleigh and Mr Isaac Gibson?

Isaac:

Argh, don't kill me, I'm just a civilian!

Major Tom:

{{Sigh}} yes, that's us.

Panel 2: The robot hands over a suitcase.

Robot Messenger:

Here's your luggage, with love from the Space Agency.

Only, not actually with love... more like apathy, really.

Isaac:

You're not a natural red-head are you?

Panel 3:

Robot Messenger:

Ignoring the non-sequitur nature of your query; honey, nothing about me is natural.

I'm a robotic avatar being operated from a remote unit in a virtual reality suite.

Isaac:

Clearly one of the cheaper models, from a factory deep within the uncanny valley!

Panel 4: The robot turns around to go.

Robot Messenger:

Don't push it, ginger nut!

Isaac:

That is completely inappropriate, you do not have G-word privileges!

Robot Messenger:

Talk to the claw, shorty.
