Re: [californiadisasters] NASA Radar Images Show How Mexico Quake Deformed Ea...



Um, mine was not. I've found most bigots cannot spell. so I proceeded with what history has shown to be true.

If it was in fact a joke, it was fairly badly done.

Ed, the immortal words of Foghorn T. Leghorn apply to Lewis' post:

"That's a JOKE--I SAY that's a JOKE, son!"

(Mexico was "cut" or "added to"--not sure which--by 10 ft/3m, as noted in
the post he was replying to. I won't comment on the quality of the joke, but
it indeed was a joke.)

(I hope, Ed, that your reply was also a joke.)

Is this what this group is going to turn into ? Badly spelled political
attacks. God, I hope not.
