Here's a still from a little-seen tv movie from the 1970's. It was a parody of the detective/cop shows of the day. The soaked girl is Connie Stevens! Sorry the quality isn't top notch on this!
Pretty good, but it was a shame the scene was so brief.
This was actually a pretty funny tv movie that spoofed every single tv detective series in the 1970's, but they were not the first to do this, because Benny Hill did a fabulous spoof of all the 70's tv detectives on his show 5 years earlier.
Connie's better wetlook scenes were on Laugh In, Hawaiian Eye and Lifestyles of the Rich and Famous.
