The Flintstones S02E27 - The Mailman Cometh

After Fred thinks he's been singled out for not receiving his annual raise, he mails his boss, Mr. Slate, a virulent letter. But then Slate visits the Flintstone residence to personally apologize for the inadvertent error and announces to Wilma that Fred is, indeed, getting his raise. Wilma, as usual, comes to her husband's aid and very narrowly prevents what surely would have been the end of Fred's career in the gravel pit. Herb Vigran guest-stars as the policeman.
