Jim Carrey dropped by the Late Show With David Letterman Wednesday, and he was a little concerned about catching something at the New York City studio. So, just to play it safe, the 52-year-old actor pretended to take the late-night host’s temperature and asked him for “a couple of simple answers” to make sure he didn’t have Ebola. He asked, following up by questioning, “Have you traveled abroad lately? Have you ever kissed a monkey or licked an airport toilet seat?” Dave had to think about that one. Jim offered, “Maybe? Well, that’s not important.” And because “you can’t be too careful,” Jim asked the TV veteran, “Are you now or do you plan to be a member of ISIS?” Not surprisingly, Dave confirmed he had no ties to the terror group. At this point, Jim removed and read the thermometer.
