... Pretty sure the only thing that would come out of their mouths if Light did such a thing would be something along the lines of:

"[i][b]AAAAAAAAH! OH GOD! THE SPIDERS, THEY'RE EVERYWHEEEEEEEEEEEERE! MY EYES! MY EYES ARE MELTIIIIIIIIIIING! WHY WON'T THE DOGS STOP BARKING!? MAKE THEM STOP! MOMMY! MOMMY! I SCRAPED MY KNEEEEES! WHERE THE HELL IS MY GRILLED CHEESE!? CATS IN THE CRADLE WITH THE SILVER SPOON![/b][/i]"
*Blood vein pops*

And then they'd [i]expire[/i]. Nice of Light to let them croak inbetween her jugs though. There're far worse ways to go, for sure. ^^
