Tells his dates that they are his dessert. When they arrive back at his place he tells them to make themselves comfortable, five minutes later he returns dressed as Hannibal Lecter.
He thinks that the phrase 'giving oral' means talking and so the conversation goes "I was giving oral to...." after the third time of him saying it his dates use their escape plan.
He suggests a romantic movie date and then brings them to "The Silence of the Lambs" and talks all the way through about how the movie reminds him of his ex, who has mysteriously disappeared.
