After rolling out the red carpet Wednesday morning in anticipation of Sunday’s Emmy ceremony, host Jimmy Kimmel warned he’s planning a prank on folks not watching the show.

“I have an idea for a prank, and if it goes well, will be great,” the first-time Emmy host teased after ceremoniously unraveling the red carpet. “If it goes badly, it won’t be so great. I think it will go well. If you’re watching, you’ll be in on it. If you’re not, you might get caught up in the prank.”

Kimmel, whose “Jimmy Kimmel Live!” received its first nomination for outstanding variety series this year, is looking forward to seeing what TV stars look like out of costume Sunday.
