Makes joke about penises while showing full frontal
David plays Harvey, husband of Maggie (Sara Stockbridge). They encounter Ashley (Craig Kelly) and Emily (Charlotte Lucas) at a nudist swimming pool. This is the first time that Harvey has seen Ashley nude. He makes a humorous comment about Ashley's penis compared to his own.
Appears fully nude (though not quite frontal) in funny shower scene.
Kristi is showering while talking to a fully-clothed Betsy Russell. (That alone makes it unusual.) Kristi shares a rumor with Betsy about the endowment, or possible shortcoming in that department, of a male friend.
What the girls don't know is that the friend, played by Cory Hawkins, is showering in an adjacent shower room and has heard their conversation through the wall. Wrapped in a towel, he steps out of his shower and into Kristi's while she isn't looking.
Kristi asks Betsy for a towel. Cory hands her his. Only after using it for a moment does she notice him--and although we don't see Cory's full monty (we get only a rear view), her reaction implies that she was totally wrong about his size.
She is awed by what she sees, and stammers out a proposition. He has a surprise reason for rejecting her, and when he leaves, she expresses her chagrin.
In addition to being great eye-candy, this scene is very funny. You can find it on DailyMotion under the title "betsy russell and kristi somers".
