You know, maybe we ought to not draw attention to some of the returnees; many of these guys were the most entertaining opponents we've ever crossed swords with. Far be it for me to tell you to not argue with a guy who thinks parrots have psychic abilities, that Saturn once hovered over the North Pole, and that ASCII bats make great pets......
;-)
C'mon! That Saturn thing was good for hours of fun! I mean, when you pointed out that it would be downright difficult for Earth, having left Saturn's orbit (through some mechanism that prevented its destruction from the energy involved) to achieve a nearly-circular orbit around the Sun, you have the creo best-and-brightest chiming in with their "wildly elliptical" arguments. Oh the joy as each post by He-who-will-not-be-named dug deeper and deeper holes as he tried desperately to twist-and-shout his way out.
You can't say that wasn't enjoyable. Now we're stuck with word lawyers...
