When Bea texted Milo and Oscar to get Bea's diary from Randy's house, Milo ran into Grammy Pincherson, who he first thought was a statue. Grammy Pincherson responded to Milo, and due to her poor eyesight, she thought he was Randy. Milo, pretending to be Randy, asks Grammy Pincherson where he keeps his diary. Grammy told Milo she will tell him as soon as he finishes cleaning her dentures, much to Milo's horror. Later when Oscar and Milo got Randy's diary instead of Bea's, they went to the school auditorium to stop Randy from reading Bea's diary in front of the whole school. They humiliated Randy by bringing Grammy to the auditorium so she can read Randy's diary in front of the school instead. Grammy Pincherson read aloud how Randy stole Bea's diary, causing the school to throw tomatoes at him ("Diary of a Lost Fish").
