Maybe those of you with more math than I will appreciate this.

this is serious engineering humor.

- -------------------
After the Great Flood was over, Noah gently eased the Ark down on top
of a Turkish mountain range.  Once everything was secured, he got off
and personally supervised the release of the animals on board.
As each pair was released from the hold to go hopping, crawling and
fluttering away, Noah said to them "Go forth and multiply!"

At one point, a pair of snakes came slithering down the ramp together.
Noah addressed them as he had all the others: "Go forth and multiply!"
The snakes looked at one another in embarassment, and then replied
"We can't.  We're adders."

Well, this set Noah to thinking.  He bid the snakes to wait there for
a little while.  Then he went down to the hold, gathered up his
carpentry tools (left over from the big Ark-building endeavor 40 days
and nights ago, I suppose), and then set off into the forest.  He
returned later dragging along a bunch of fallen logs.

Then there was furious activity: Noah was sawing, planing, hammering
away at the logs.  When he was finished, he presented to the snakes a
newly built, rough-hewn table.  Then he said to them again, "Go forth
and multiply!"

"But we're adders!" the snakes moaned.  Noah said, "Yes, but I've just
built you a log table!"
