Geek Couple at Work

Yes, I IM with my husband from time to time while we are at work. Here is an example of how geeky we are:

Husband: Here's a brain teaser for you.
Husband: 1=5, 2=25, 3=125, 4=625, 5=??
Sent at 10:05 AM on Tuesday
Me: Oh come on
That is too easy
3125
Husband: Or is it...
I didn't ask for the next number in the series. If you look back 1=5 therfore 5 must = 1
Me: Assuming it was an equation
Assuming it was pattern matching, or an equation to solve
If it is pattern matching, that is the wrong answer
If it is a mathematical problem, that is the right answer
Even then it is not the right answer. In math 5 cannot equal 1
The whole premise of the question is flawed if it is not a pattern matching question.
Husband: Someone sounds bitter.
an even worse answer would be ? since it also said 5=? but I won't go there.
Also there are no units shown 1 can equal 5 depending on the units.
Me: I'm not bitter, just right
If no units are shown, there are no units.
Husband: You're right. Also if the units are different than they are not equal they are equivilant.
Me: who gave you this "brain teaser" you should harrass them
Husband: Coworker. I will
BTW. I answered the same as you.
Me: Good, because that is correct :)

Sums up our entire relationship.
