Y2K Bunker

Jim sees his neighbor out back building a bunker, loading in 75 gallons of bottled water, hauling in a gas generator and so on. "So, uh, I guess you believe Y2K is a biggie huh?"
"Naw", says the neighbor. "Ah's jes' stockin' the bunker now, 'cuz if I did it any other time, people'd think ah's nuts."
