Meredith Vieira Pranked By Ellen (VIDEO)

Meredith Vieira appeared on Ellen DeGeneres' Monday show to talk about her exit from the "Today" show.

Of course, Ellen loves nothing more than pranking people, and Vieira screamed--and swore--impressively when Ellen, who had been lurking in a bathroom, jumped out and startled her.

"You have a filthy, filthy mouth!" Ellen said. "I don't know how you've lasted on television all these years."
