I wish the video quality was better, and the sound synchronized with the picture, but . . . man! Am I hearing Dawn Wells say the word FIVE TIMES IN A ROW?!
It's from the TV movie called 'The Castaways On Gilligan's Island' - 1979
The man that MaryAnn (Dawn Welles) was trying to foot tickle is Tom Bosley (Howard Cunningham on Happy Days)
