So, I just got off the phone with the FBI.

There's something mysterious and exciting about the FBI saying they want to interview you about an issue of national security. It becomes somewhat less exciting when you discover that they only wanted to talk to you because of an error in their records about where your office is and how much clearance you have.

Apparently, my official records list me as having a high security clearance and having an office near where the hard drives disappeared over at the lab. I was this close to getting a polygraph. Damn.

So at Kevin's birthday party last night, I ended up making "chocolate mousers" for a bunch of people. It seems to be a popular drink.

Afterwards, we went to Joy's place to watch Law & Order. There, I met the fatest cat in the universe, Romulus. Robbie and Dallas and I threw riddles and math puzzles at each other until 4am.

If you've seen Die Hard 3, then you know this one: You have a 3 gallon jug and a 5 gallon jug and an infinite supply of water. How can you get exactly 4 gallons into the 5 gallon jug?

Here's another popular one: There are four people trying to get across a bridge. No more than two people can be on the bridge at one time. Furthermore, any person or pair of people crossing the bridge must carry the flashlight with them. The people move at different speeds. They can cross the bridge in 10 minutes, 5 minutes, 2 minutes, and 1 minute, respectively. Because there is only one flashlight, a pair of people can only cross the bridge at the speed of the slowest person. What is the shortest amount of time you can get everyone across in?

One more: You have 8 coins. You know that all of the coins have the same weight except one, which is lighter. How many measurements on a balance are necessary to determine which coin is the light one?
