Josh Duhamel [1] stopped by The Ellen Show on Thursday in full Halloween mode [2]; the actor dressed up as Lloyd Christmas (Jim Carrey [3]'s infamous Dumb & Dumber character) and sat for an interview with Ellen DeGeneres [4], who had just debuted her "Karla Kardashian" costume [5]. After showing off an impressive Jim Carrey impression and talking about his and wife Fergie [6]'s penchant for dressing up, Josh became the latest target of Ellen's signature scare prank — and this time, it came with a twist. Watch the video above now, and then see what happened when Ellen sent Modern Family's Eric Stonestreet to a haunted house [7] this week.
