[in a cabin in the mountains, Jim wakes up and bangs his head on the table he was sleeping under]
Alex Rieger: Jim, are you alright?
"Reverend" Jim Ignatowski: Yeah...uh ... who are you?
Alex Rieger: I'm Alex. We're friends, we work together.
"Reverend" Jim Ignatowski: What? are we, lumberjacks?
Alex Rieger: No, we're cabdrivers.
"Reverend" Jim Ignatowski: I bet we don't do much business up here!
And we all know how often divisibility-by-seven is needed in our daily lives....
But if you DID need to know a shortcut, it would be: take the last digit, double it, and subtract it from the rest of the number example: 301 you take 1, double it (=2), and subtract it from 30. That gives you 28 which is divisible by seven... so 301 is divisible by seven. (no, really)
See? There are nerd lumberjacks. Other seven facts: 1) You can get seven squirrels in a Ford F150's glove box. (of course, you can always get *less* than seven, but why would you want to?) 2) There are that many "deadly" sins. Coincidentally, there are also that many "fun" ones. (3 of which involve chocolate) 3) it's a prime number. (which means it's a really, really good one) 4) 7 inches is how tall the Leatherface action figure stands. (Texas Chainsaw Massacre)

Dang!! And here I was all ready to do some seven-dividing. Quel domage...
(My old method, where you just divide it by seven and see if there's a remainder, seems to work pretty well, but I keep hoping there's a better way.)
