Paul Tate is an unseen character who is mentioned in Honey, I Shrunk the Kids.
Amy brings him up once in a while, such as whether he invited him to a dance party, and that at 5:00, she would meet him at a mall. It was mentioned that he and some girl (presumably one named Barbara) had broken up because he disagreed when she said she was God. Later, in a phone call between Amy and Diane, the latter asks the former if Paul asked her to the dance. And finally, when the kids are shrunk and the phone rings, Amy threatens to kill Nick if it's Paul.
