Charger: Yo, Phone.
Phone: Yeah?
Charger: Can I plug all in you?
Phone: Ayooo!
Charger: Yo, Phone.
Phone: Yeah?
Charger: Can I plug all in you?
Phone: Ayooo!
Okay, so listen up, nimrod. The joke is that the charger asks the phone if it can "plug all in" to it. This sounds like a sexual innuendo, like someone asking to have sex. You probably use a charger every day, but you're too dumb to realize the double meaning here. Sad!
