The jeep driven by Rosemary and Laura is the same one (Reg. MA.0369.M) they drive in Agua Cadaver (2006).
While shopping for palm trees, Rosemary has a large black spider on her arm. She swats it several times with some paper and then complains that it bit her. What did she expect. She would have been better off to slide the piece of paper gently under the spider and placed it somewhere.
