The Water Nymph
Seems like some footage may be missing because in the first scene Sennett gives Mabel a ring and a kiss, in the next scene he's crying with suitcase in hand, surrounded by his parents - but the reason is never revealed. In the next scene he tells Mabel to vamp the father - again, no reason given. Seems possible that this is a story of forbidden love, with the vamp used as blackmail. But this is never even hinted at - and Keystone did not build its comedic reputation on subtlety. So this ends up as mainly a showcase for Mabel's diving stunts, with help from Ford Sterling's tits-up-butt-out shtick.
