Interpretations vary wildly sometimes.

Nursing Home Caller: I need to call in orders for a patient who is being discharged.
CP: Okay. How many do you have?
CP: How many?
NHC: A couple.
CP: Uh-huh. Sure. No one gets discharged from a nursing home on just a couple. What's a couple?
NHC: I don't know. Like 8 or 9?
CP: Seriously? You call that a couple? When was the last time you were at a wedding where the priest introduced the "Happy Couple" and you saw 8 or 9 people standing at the altar?
