Technically I got 3.5 hours of sleep last night, but close enough that I was in a pretty sour mood all day. And yep, that’s the actual line from the episode (S4E11: The Auction)

(Dorothy sees Rose carrying two buckets )

Dorothy: Oh, hi, Rose - is the ceiling in your room leaking, too?

Rose: No, Dorothy. I just finished milking the cow I keep in my closet. Gee, with only three hours’ sleep, I can be as bitchy as you!
