It would be bad.
The bad part is that oil floats on water so any water you put in sunk right to the bottom of where ever you put it.
But all is not lost, since you know what you did as long as you change the oil VERY SOON all will be well.
When I said change the oil "SOON" I mean that at the very most the car could be driven directly to a mechanic. At the very best the engine would not be run at all and the oil changed before the engine is started at all and the water/oil mixture be turned into mayonnaise!
