Dammit Desmostylus, we’re mostly Australians in this thread. Surely I don’t need to use smilies for you to know I’m joking? 🙂

> The male lands about 10 cm from a female, his ventral surfaces facing hers. He extends his erect penis toward the female by holding his pelvic region forward. His wings are fully extended, with the leading edge of the wing approximately perpendicular to the long axis of the body. The two wings are flapped forward and back simultaneously and in the same direction, in an arc of about 45 degrees. At the same time, the penis is ‘waved’ side-to-side in a narrow arc for about 5-8 s. As the wings are moved, the male may take several steps toward the female.

I seen a guy do this in a raincoat once.
