Sebastian was nicknamed "Slam" because she would suddenly pass out cold after a few drinks.
Buster Keaton, her lover in the late 1920s, turned this disconcerting habit into a classic gag routine in his film
Spite Marriage (1929), in which Keaton tries to put his very drunk newlywed wife (a game Sebastian) to bed. It was a career highlight for the actress, and Keaton revived the gag as part of his stage show in the 1940s.
