When the Wayans brothers first enter the hotel as the Wilson sisters, one of them accidentally knocks over a souvenier stand that spills pens all over the counter. Notice that before the camera moves to the man at the check-in desk the pens are scattered all over the counter. Then when the camera is back on the girls, the pens are neatly tipped over in a plastic tube. Then, once again, they're scattered all around. Those are some weird pens!
