Angel from Hell - Season 1 Episode 4 Family Business

Allison, who along with unsolicited and unwanted advice from Amy, finds herself dealing with trying to run the office while Marv volunteers to join Brad on a trip that he booked for him and his ex-wife a year in advance. Unfortunately for Allison (and unpredictable advice from Amy), the situation of being in charge is made worse, as is the trip for Marv and Brad. In the end, Marv decides to make Allison a full-time partner, just in time for Amy to give Allison a long-awaited surprise gift that she ordered long before the fiasco... a mug that reads "Fuller & Fuller Dermatology."
