Check out my favorite family, The Simpsons, and its recent episode, "Thank God It's Doomsday". I couldn’t help but think that one scene illustrates how the GB arrives at their many date predictions over the years.
Homer, at the kitchen table reading studiously: "Hmmm. Hmmm."
Marge: "Homey, you haven’t touched your second dinner tonight -- and [noting the kitchen table covered with thick reference books] you’re reading books. What’s going on?
Homer: Marge, the Rapture is nigh. Each book will help me figure out how nigh. This whole deal is scientifically proven.
[Homer begins to illustrate his ciphering on chalkboard]
"The book of Revelation[s] has 404 verses. Add the number of people at the Last Supper, 12, minus the number of Filipinos in the Bible, 0, and you get ..."
[chalkboard displays several math like expressions:
12 - 333 x 666 =
(a x b2) > 2 = 7
(2 + 2b2) - 144,000]
Marge jumps ahead: "Three million one hundred ..."
Homer, rudely interrupts his novice wife: "whoop, whoop, whoop, whoop! Three-fifteen pm, May 18th. That’s when the Rapture will begin."
Marge: "May 18th? That’s one week from today."
Homer: "A week?" [appears puzzled and jealous at Marge’s quick deduction. To prove her wrong, more rapid chalkboard calculations. Then, as if he’s inspired with his own profound conclusion] "That’s (pause) seven days from now!"
Most of the town of Springfield follows him to the Springfield Mesa, west of town but the rapture never comes. Undaunted, Homer discovers an error in his calculations and returns to the Springfield Mesa alone, where he experiences a satiric conversation with God.
