Jim Carrey’s Joe Biden was a rhyming machine — Edgar Allan Poe style — during a Halloween-themed cold open for the last “Saturday Night Live” before Tuesday’s election.

“It’s a spooky time filled with demons and darkness. Also it’s Halloween,” Carrey’s Biden said of the Saturday night holiday. “For some Trump voters, it’s the only day they’ll wear a mask.”

Biden joked that the spooky decorations were from First Lady Melania Trump’s Christmas collection but pointed out that folks were “very, very worried” about the outcome of the election. “They say I’m eight points ahead – poll numbers like that can only go wrong once in a blue moon.” He looked out a window and s a blue moon. “That’s a little troubling.”

Then Biden said he wanted to tell a scary story — not Donald Trump Jr.’s “Triggered” (“That one’s a little too scary”) but instead a tale inspired by the macabre Edgar Allan Poe. “In the 1800s, people would read this and soil their pantaloons.”

Played by Kate McKinnon with raven’s wings, Hillary Clinton was the first special guest. “You may be scared of four years more,” Biden said of Trump’s reelection. “Quoth the Clinton…” “We lost before,” Clinton finished. And when Biden stated, “All the votes will be accounted for,” Clinton quipped, “Just like Al Gore.”

The opening also featured appearances from Kenan Thompson and Chris Redd as Trump supporters Ice Cube and Lil Wayne, plus Beck Bennett as Mitch McConnell.  “Don’t tell anyone this but I’m kind of pulling for you. You’re doing great,” said McConnell, whose discolored hands were mocked by Biden. His reply: “This is just a common condition called ‘Old man purple.”

Carrey’s Biden was then joined by his running mate, Maya Rudolph’s Kamala Harris, for a couple parting messages for the American people.

“Use your voice and use your vote. Democracy will represent,” Harris said.

Added Biden: “This Daylight Savings Time, let’s gain an hour and lose a president.”
