Back before Route 66 made crossing the desert easy, three friends wanted to cross the Mojave. Of the three buddies there was a “smart dude,” a “not so smart dude,” and a “not smart at all dude.” Before they left the “smart dude” says, “We’ll meet here in an hour. Bring something useful to cross the desert with.”
An hour passes. All three friends return.
The “smart dude” says, “I brought some ice packs to keep our heads cool.”
The “not so smart dude” says, “I brought a pail of water to keep us properly hydrated.”
The “not smart at all dude” smiles real broad and says, “I brought a car door so I can roll down the window when it gets hot.”
