OK, hard act to follow.  My favorite nerd joke is from Dilbert (paraphrased): Does an engineer see the glass half full or half empty?  Neither, the engineer has two redundant glasses in case one spills.

• Dragonsbreath

My variation is that an engineer see’s the glass as being twice as big as it needs to be.

thank you.  I loved most of this and have to find an opportune moment to try the last physical prank at home.  no way that works.

My favorite: Why do programmers confuse Christmas and Halloween? Because 31(oct)=25(dec).

• Nick Hayday

Of course it does if you assign it, 31(oct)==25(dec)

• 8bar

You do understand I’m talking about octal and decimal, right?

• Nick Hayday

Yes, but one equals sign is normally assign, and two is a boolean test

• 8bar

I hail from the old FORTRAN days, where = was both an assignment and a logical test! But I like your modernized version better, 31(oct) == 25(dec).

I have been liking this one recently:

A mathematician, an engineer, and a physicist are being interviewed for a job. In each case, the interview goes along famously until the last question is asked: “How much is one plus one?”

Each of them suspects a trap, and is hesitant to answer.

The mathematician thinks for a moment, and says “I’m not sure, but I think it converges”.

The physicist says “I’m not sure, but I think it’s on the order of one”

The engineer gets up, closes the door to the office, and says “How much do you want it to be?”.
