The Toad line is one of Joss Whedon's two contributions to the X-Men script (the other being Wolverine's "You're a dick"). According to Whedon, it was originally written almost as a Buffy-ish line.
(Cocky

"You know what happens to a toad when it's struck by lightning?"
<Toad gets fried, goes flying offscreen.>
(Sardonic, grinning

"Huh. Same thing that happens to everything else."
Granted, it's not MUCH better, even when you imagine the proper delivery, but it's infinitely better than Berry's voodoo goddess delivery ("De SAME t'ing DAT 'appens to eddyTING else!"). It should have been axed from the script, it should have been axed from the shooting, and it should have been axed during the editing. The fact that it survives in the final cut is ridiculous.
That has nothing to do with X2, of course, but I just thought it was mildly interesting when I read it.
