Dr. Keats: Little Sammy Sosa's a bit shook up, but she'll be okay. She's watching the tape as we speak.
Henry: Good. How's my temporal lobe looking there, Doc?
Dr. Keats: Don't worry. You're not gonna suffer any short term memory loss. But was your head shaped like an egg before she hit you?
Doug: Hey! Don't make fun of Henry, all right? It'th not hith fault hith head'th thaped like that.
Dr. Keats: Note the intense overreaciton. That's the 'roids talking.
Question: When Henry and Lucy are getting intimate and Henry sees the two dolphins in the tank watching, he calls them Mary Kate and Ashley. I know who they are but why does he refer to them like this?





Answer: Probably because it was the dolphins' names. Someone probably thought the dolphins looked alike and that it would be funny if they were named after the famous twins.
