On the show's finale Monday night, tennis star Mark Philippousis was tickled. He and Jen, the 48 yr old, were having their final date at the Melbourne Aquarium. After dinner, they are laying in a pile of blankets looking at the sea life. The camera cuts to Mark as he asks, "Ticklish?" She says, "No." He tried to tickle the outside of her armpit to no avail. She asks, "Are you?" and he freaks and says, "Yes!" The camera cuts to another angle and she is touching his ribs (his arm is over his head) and he is pulls away. She says, "I am barely touching you." Then she digs her fingers in harder and he laughs again and pulls away.
