What's the difference between my phone and my sister?
I actually give a damn if my phone dies.
The joke plays on the idea of valuing a phone more than a family member, specifically a sister. It uses dark humor to highlight a lack of care for a close relative by contrasting it with the concern one would have for an inanimate object. It's a morbid twist on relationships.

I know right? My sister's an a..hole.
Zane
Hey guys, How's it going?
Zane
F...! I'm in a paradox.
Zane
Tell my girlfriend I love her.

Also, tell my sister to f... off.
