You've managed to get dressed merely by touch (probably, too much touch, honestly), but neglected to lay out your socks the previous evening. In your sock drawer you have 6 pairs of navy blue socks and 6 pairs of black socks and a copy of Gentleman's Quartely, the magazine that usually features coins dressed in small business suits and tuxedo's, but this is the swimsuit edition. You decide to just grab a bunch of socks and put them on before going out the front door. You have only one leg because of a horrific car accident three years prior. The population of the world is currently suffering from a strange ocular disease that has left its entire population colorblind. Because of a strange allergy, whenever the color navy blue touches your skin, you feel like someone put itch powder in your sleeping bag. You don't own a sleeping bag. Anymore. Your roommate has been known to borrow your black socks for, um, "interesting" purposes and, before bed, you did notice he was watching the Kristy Swanson/Stephen Baldwin erotic thriller Bound by Lies.

What's the MINIMUM number of socks you need to grab to ensure you can fuel your jetpack that is powered by sock consumption?"

Pour the one gallon remaining in the three gallon jug into the five gallon jug. Fill the three gallon jug, and pour it into the five gallon jug. (1+3=4) Ta-da! (There is more than one possible solution, so I'm not sure if this is how it was done in the film...)

Fill the 3 gallon jug with a full five gallon jug. This leaves two gallons in the fiver. Empty the three gallon jug, and then dump the two gallons from the five into the three. Now, refill the five. At this point, all you need to do is fill up the remaining gallon space in the three gallon jug with the fiver, which will leave the fiver filled with four gallons.

The upshot of this one is that you only waste three gallons, unlike LD's solution, which will lead to five gallons lost forever YOU WASTEFUL BASTARD
