Visible crew/equipment: In the scene where the piano collapses, after Madea's chainsaw rampage, you can see the wire that pulls the piano apart.

Continuity mistake: In the scene where Helen wheel-chair pushes Charles to the bathroom for his first bath, she dumps him in the tub and we see water covering his clothes, yet in the next shot, Charles' left pants leg appears dry.

Helen: Orlando, what's going.
Orlando: I know you don't believe in fairy tales. But, if you did, I'd want to be your knight in shining armor. You've been through so much. I don't want to see you hurt anymore. Now I may not be able to give you all that your used to. But I do know I can love you past your pain. I don't want you to worry about anything. You just wake up in the morning, that's all you have to do and I'll take it from there. There's one condition. You have to be my wife.

Joe: Who dat is at the door?
Madea: Shutup Joe I got this.
Joe: I'm gettin' tired of all these people comin' ova here late at night, I'ma hafta put my foot down.
Madea: Kunta Kinte put his foot down and it got chopped off. Now shut the hell up and go back to sleep.

Madea: I remember this dude made me so mad, I didn't even know how mad I was until I went to his funeral.
Helen: Why were you so mad at him?
Madea: Because he hit me. Yes he hit me... and I didn't even know how mad I was until I saw him in his casket, he's 8 feet under.
Myrtle: 6 feet, that's how they bury people, Madea, 6 feet under.
Madea: That's what I'm trying to say, I thought I was over what he did to me until I saw him at the funeral, I was so mad I beat HIM down 2 more feet.

Question: If Helen is related to Madea on her dead husband's side, how is her grandmother, and what what relation is Helen's mother Myrtle to Madea?
