Reminds me of an old joke. To file off the serial numbers:
What's worse than getting a pregnant Brontosaurus into an ark?
Getting a Brontosaurus pregnant in an ark!
[Hey, quit rocking the ark, Noah's trying to sleep up here.]
...talk about your Brokeback 'Mounting...
BTW, would they use the "Missionary Position" (being evolutionary artefacts, and all?)
Cheers!
