Mother-In-Law's Day (1945)

Edgar Kennedy finally works up enough courage to evict his in-laws, Florences mother and brother. That same day, Edgar's boss gives him a raise because his boss likes people who take care of their mother-in-law. And, since it is Mother-in-Law's Day where Edgar lives, his boss drops by that night to pay his respects to Edgar's mother-in-law. Edgar, in order to not let his boss know he has kicked his mother-in-law out of his house, dresses up like her, and takes to bed claiming to be ill. No good can come of this...and none does.
