Arsenic and Old Lace/Funny

• Jonathan slowly coming to the realization that he and his kindly old aunts have murdered the same number of people.
• The aunts' latest "charity case" is handed a glass of the elderberry wine while Mortimer tries to reach the sanitarium on the phone. After hanging up, he distractedly grabs a glass of his own. The aunts warn him off, he realizes what he's doing and puts the glass down...and seeing the visitor about to drink, lets out a piercing shriek of horror.
• "Insanity runs in my family. (Beat) It practically gallops!"
