When I was living in Vegas, my sister called me up on a Sunday morning because she needed a ride to Reno(where we grew up).  Mind you, that's a nearly 8-hour-drive, so my hungover, stinky, unshaven ass was pissed off that I had to pick her up and put in a full shift.  I pick her up and not only is she still hammered, but she has a black eye because she literally fell into a doorknob.
Four hours later, I'm pulled over for speeding in the middle of nowhere, cologne de whiskey and gnarly half-stubble while a cop is looking at my sister, then at me, then at my sister.  He asks if she's ok, and she slurs some shit at him and throws up.  I start to say "She's a little drunk still.  I'm giving her a ride and no, I didn't beat her." but he cuts me off at "I'm gi" and screams "WAS I TALKING TO YOU, PUNK!?"
In the end she came to long enough to explain our way out of both jail and a ticket.
