A guy spots a sign outside a house that reads "Talking Dog for Sale." Intrigued, he walks in.
"So what have you done with your life?" he asks the dog.
"I’ve led a very full life," says the dog. "I lived in the Alps rescuing avalanche victims. Then I served my country in Iraq. And now I spend my days reading to the residents of a retirement home."
The guy is flabbergasted. He asks the dog’s owner, "Why on earth would you want to get rid of an incredible dog like that?"
The owner says, "Because he’s a liar! He never did any of that!"

A boy comes to his father and is curious about what a vagina looks like.
Dad: Well son, before sex, it looks like a beautiful rose, with beads of dew glistening on the petals.
Son: Ok...what does it look like after sex?
Dad: Well son...picture a bulldog eating cottage cheese.

The dirty jokes are pretty terrible, but some of these are gold!
I was going to put my favourite but it's already in the OP (though I remember the punchline as "Do you know how to drive this thing?" - I think it was on the spine of a PC Gamer UK issue :P).
My other favourite corny joke is also one I learned from computer games - in this case the SimCity 2000 credits!
Three strings walk into a bar.
The first string shouts to the barman, "Oi! Gizza beer!". The barman points to a large sign that says "NO STRINGS ALLOWED", and croaks, "we don't serve your kind here," then kicks him out.
The second string thinks maybe it's worth being polite and says to the barman, "excuse me, kind sir, but could I trouble you for a beer?" The barman goes red with anger and shouts, "I SAID, WE DON'T SERVE STRINGS HERE!", takes one end of the string and tosses him outside.
The third string thinks for a minute, then goes to the restroom, loops himself around a couple of times and musses up his hair. He goes back to the bar and says, "Oi! Gizza beer!"
The barman squints at him and says, "aren't you a string?" String says with a smile, "no sir, I'm a frayed knot."
A frayed knot - afraid not - get it? :D

Very well, a geeky joke:
A byte walks into a bar. The bartender asks "What's wrong with you?" "Parity error", the byte replies. The bartender says "Yeah, I thought you looked a bit off".

Not so much a joke really, but corny it is.
10 ways to amuse a math nerd:
01. Make a list of ways to amuse a math nerd
10. Do it in binary

That reminds me of the joke, "There are 10 types of people in this world, people who understand binary, and those that don't."

Bah, that's what I get for not typing these down, I knew that one I did. Also, somewhere on the same track:
There are 3 types of people in the world; those who can count and those who can't.

4/3 people don't understand fractions.
