Marvin learns what an expiration date is, and he thinks that Pop-Pop will expire when he sees his driver's license. The day before Pop-Pop was supposed to "expire," he says that the bacon is going to expire in one day so Bob tells him to freeze the bacon to keep it fresh. So he freezes Pop-Pop. Marvin, Henry, Liz and Bob soon discovered that Pop-Pop was tricking Marvin so he can get whatever he wants. Upon unfreezing him, it is unveiled that Marvin tried to make a device to make Pop-Pop young again. But it backfired so he is now an elderly. He was about to die, so he asks Bob to make him a smoothie as his last wish. It is revealed that he only set his cloaking device to "Old Fart". Meanwhile Teri and Briana plot revenge on a boy who has asked them both on a date only to find out that the boy is actually a twin. (thetvdb.com)
