If everything happens for a reason, then perhaps Jenny Slate had to stumble upon a stranger’s urine collection and step on his floor burrito (which was 100 percent a full adult diaper, no doubt about that) as part of her journey to her pup Reggie. Alternately and vastly more likely, Jenny Slate ruined her shoes and her hopeful young mind in an opera singer’s crack den for absolutely no reason. Either way, all dogs are from, and go to, heaven. That part is well-recorded science.
