Factual error: Diane says that her parents named her Diane because they liked the show "Cheers." However, she recently turned 35, and this episode was created in 2015. She was born in 1980, but the first "Cheers" episode was in 1982.
Other mistake: When Diane and Mr. Peanutbutter accidentally met at the bar, they first make eye contact. But Mr. PeanutButter being a dog, he would have recognized her smell as soon as he entered the room. (00:16:40)
Mr. Peanutbutter: The universe is a cruel, uncaring void. The key to being happy isn't the search for meaning; is to just keep yourself busy with unimportant nonsense, and eventually, you will be dead.
