To lighten your holiday season, here is some science fiction humor, gleaned from around the Web.  First, some groaners:

How many ears does Spock have?
Three. A left ear, a right ear, and a final front ear.

What do you call an invisible robot?
R2-C Thru

Speaking as a writer, this next  one is almost more painfully true than funny.

There was once a young man who, in his youth, professed his desire to become a great
writer.

When asked to define “Great” he said, “I want to write science fiction that the whole world will
read, stuff that people will react to on a truly emotional level, stuff that will make
them scream, cry, howl in pain and anger!”

He now works for Microsoft, writing error messages.

Speaking of writers …

Science fiction author Alex Bledsoe references a movie for his personal Favorite Science Fiction Joke … and it’s a goodie.

Visual humor

Several cartoonists have a great sense of science fiction humor.  One that I particularly like is Mark Parisi’s OffTheMark.com.  Here are a couple of his beauties, just to give you a taste.

And here’s my own rendition of R2-C Thru.  Tell me honestly: Do I have a future as an artist?

========================

For men only beyond this point.  All earthlings of the female persuasion, please stop reading now.  You’ve been warned!

Finally, some science fiction pick-up lines that are guaranteed to elicit a slap in the face, or perhaps a kick in more painful places.  I hereby disclaim any legal responsibility for medical costs associated with people dumb enough to actually try these:

• Your mouth says, ‘Shields up!’, but your eyes say, ‘A hull breach is imminent.’
• I can’t help it — my eyes are trapped in the gravitational field of your breasts!
• Why don’t we head to my bedroom, peel back my Star Wars sheets, and discover what a true Jedi can do with his light sabre?
• Honey, you’ve been looking for love in Alderaan places!
• I may look like an Ewok, but I’m all Wookie where it counts, baby.
• What’s a girl like you doing in a place like this when there’s a Farscape marathon on right now on the Sci Fi channel?

Have any good jokes to add to the list (science fiction or otherwise)?
