Margie and Luke (who is deaf) won another leg of the CBS competition Amazing Race in the episode that aired Sunday night, earning themselves a free trip to San Juan, Puerto Rico. Margie was quick to figure out how to attach a propeller to the long-tail boat using a set of tools.. Teams also had to match five dental patients with an appropriate set of false teeth. Luke's struggle with the task was funny. The long-suffering patients patiently let him shove poorly fitted dentures into their mouths. No one was eliminated.
