OK...I am totally weirded out.
First of all, I don't go to bars. Haven't been to a bar since I was in my 20's...and that was a good, long time ago. I rarely drink. Hence, I am very unfamiliar with "bar talk."
What I'm weirded out about is the sheer number of times I've turned to my husband - or he to me - and said at the television set "he could be so-and-so's younger brother." Or older brother. Or even "cousin," if the resemblance needed an extra gentic jog sideways. It's something we do a lot and kills time during mediocre television shows or movies.
256 molds. Based on the binary system. Once the molds and all the variants thereof are used, they rotate back to the beginning. Seems logical.
OK, Mr. Wizard, since you started this, solve the equation for "x." How many variations are there?
(I desperately wanted to post "Dravyk, you're totally insane" and be done with it...but honesty won out, as it is wont to do.)
