Von Dutch! Ed Hardy! Jessica Biel!
Wait, which of those was a real person again? Note that BoJack punnified the first two, giving Mr. Peanutbutter (Paul F. Tompkins) a "Swan Dutch" trucker cap and a T-shirt emblazoned with "Sit, Fetch, Stay."
While Peanutbutter waits in line for Starbucks, he discusses career opportunities: "My flip phone is blowing up with opportunities... Michael Vick made me a very strange offer." We're guessing the pup passed on that one.
Mr. Peanutbutter's second ("and final!") wife was Jessica Biel -- voiced by the very game Biel herself. Or as she puts it: "The girl from 7th Heaven who took all her clothes off for that magazine."
Oh, and be sure to read that drink board. In an interview with Vulture, Hanawalt cited it as one of her favorite BoJack sight gags, ever.
