She was the blonde bombshell, a la Marilyn Monroe/Jayne Mansfield, who wound up staying at Muldoon and his mom's house!
This classic episode has some very funny material in it. Lisa Loughlin does a very nice job of playing the harassed movie celebrity "Teresa Tangiers" and the expressions on Muldoon's face were priceless. Fred Gwynne's (Muldoon) acting is excellent. Some of the cast usually got more laughs but Gwynne was an underrated comedy actor.
It also was interesting to see the rest of Muldoon's family, something that wasn't usually seen.
