What are the motifs in Oh Dad, Poor Dad, Momma's Hung You in the Closet and I'm Feelin' So Sad by Arthur L. Kopit?

A common feature in the Theatre of the Absurd is a farcical treatment of both death and the dead, matters that are normally treated with solemn reverence. It is their disrespectful and at times zany approach to such things that explains these plays' paradoxical description as tragifarces. In a very twisted sense, Oh Dad is a threnody (a dirge or lamentation of loss). Initially, Madame Rosepettle is decked out in mourning black. She and her son accompany the coffin of her departed husband in something like a funereal procession. She even totes around black drapes, used to cover the windows in the master bedroom, where she keeps Albert Edward Robinson Rosepettle III's remains in the closet, as if the suite somehow serves as a transitional mortuary for the yet to be buried corpse.
