Unexpectedly Jimmy becomes Lingual’s (Bob’s ex-girlfriend) new boyfriend. She also accelerates things by telling Jimmy she loves him.
The guys’ best friend Jane is going through the same thing as Lingual with her boyfriend Charles. Not ready to say “I love you” back to Lingual, Jimmy gets Bob’s help, and learns the secret methods of saying “I love you” without actually saying it, as well as all the many work arounds in keeping a relationship status quo from over eager girlfriends wanting more.
Jimmy manages to screw up all the techniques on Lingual, and when confiding with Jane about his screw up, they both realize Charles used the same secret techniques on her.
