Not a whole lot was said, but he found it hilarious.

... and Juliette Danielle (Lisa) has seen it as well:

At first, Juliette was stung by the press attention, particularly when it focused on her physical appearance. "On the Rifftrax"—that's the downloadable accompanying heckling track, led by former "Mystery Science Theater" host Mike Nelson—"they called me the 'bloated corpse of Britney Spears,'" she said. "It's funny when it's somebody else but God, I was just in no way prepared for that." A scene in which Juliette appears to have a bulging vein in her neck also received a great deal of attention, with fans yelling, "Kill it before it dies!" at the screen.
