See we used to have phone books that had everyone's number and they would go A to Z the joke is you think they called the whole phone book, but in reality they just called the two biggest gossips who would just so happen to be the first and last people in the phone. The joke plays on your expectations as well as doubles as a joke about extended family being annoying which is a classic trope that is reiterated in many shows such as Bob's Burgers
