Sisters Sonja Foust and Joanna Pendleton are the parody pair behind Sispoof.

Sonja Foust is an author and blogger. Most often, you can find her at Pintester.com, her humorous blog of Pinterest tests gone wrong. When she’s not busy cackling at her own jokes, you can find her singing to her dog, reading a romance novel, or watching YouTube.

Joanna Pendleton is an elementary school librarian and a mom to a clever two-year-old girl and a very active Dragon Baby fetus. When she’s not busy wrangling small children, you can find her reading for her neighborhood book club, crocheting, or sleeping.
